Actually, his statements are contradictory...



"... we must
never take laws into our hands..."


"... That is the
only way we can fight somebody..."


How can you advice people not to take the laws into their hands and simultaneously give them a reason to fight?

its cool to try something new but the whole idea should be implemented... Architecture should meet three requirements firmitas(durability), utilitas(functionality) and venustas(beauty) as stated by Vitruvius... this so called hotel failed to meet up with utilitas...I.e. it lacks functionality...
A structure for living space should at least provide shelter, privacy, security e.t.c....
I would have commended the Architect is he had provided some sort of mechanism to allow for these functions... perhaps a glass covering would make it more decent even if privacy would be compromised.
Just criticizing tho....don't term me a hater... I respect the Architect...#thinkoutofthebox

actually, the snapshot only reveals an instance during which both men transported that rod together with the load. let us assume there was a net displacement of the rod from left to right. Both men have the same displacement vector (Da = Db = xî) in unit vector notation with respect to an origin at the lower left of the picture.
To talk about WORK-DONE by both men in the language of physics, we must have sufficient information on the horizontal component of the forces they applied, we lack such information. the forces of reaction and load DOES NO WORK as their line of action is perpendicular to the net displacement vector (xî).

In conclusion, based on the information given, we shouldn't talk about who is doing more work but who is applying a greater reaction force I.e. who feels the impact of the weight of the load the most. I have already proved man B is the man in question earlier on.

Before I make my submission or give a clue, I will like to ask my friend @XXX5 if he has heard of FBD?

First, well need to consider forces and the number of forces acting on the load.

There are four forces acting on the load and they are as follows:

*F Normal
*F Friction
*F Applied
*FGravity.

1. Applied Force
F app
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.


2. Gravity Force
(also known as Weight)
F grav
The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation:
Fgrav = m * g
where g = 9.8 N/kg (on Earth)
and m = mass (in kg)
(Caution: do not confuse weight with mass.)


3. Normal Force
F norm
The normal force is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. On occasions, a normal force is exerted horizontally between two objects that are in contact with each other. For instance, if a person leans against a wall, the wall pushes horizontally on the person.


4. Friction Force
F frict
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion. Friction results from the two surfaces being pressed together closely, causing intermolecular attractive forces between molecules of different surfaces. As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. The maximum amount of friction force that a surface can exert upon an object can be calculated using the formula below:
Ffrict= µ • Fnorm

5. Air Resistance Force
F air
The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas.


6. Tension Force
F tens
The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.

7. Spring Force
F spring
The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it. An object that compresses or stretches a spring is always acted upon by a force that restores the object to its rest or equilibrium position. For most springs (specifically, for those that are said to obey " Hooke's Law", the magnitude of the force is directly proportional to the amount of stretch or compression of the spring.

I'll be back soon.
React to these above!

I identified every one of those forces
we can ignore force of air resistance because the snapshot tells us the system is momentarily at rest...
we can ignore forces of static friction between the shoulders of both men because there is no tendency for motion of the rod.
the normal forces are my Fa and Fb. the applied force is W.
We cannot determine the force of gravity acting on the body... this is because there is no information on the length, mass and position of center of mass/gravity of the rod.

havocypie:
You made no point.

perhaps you may have to read the last paragraph

TONYE001:
Mr. A is carrying the heavier load, I believe.

Why is this so?

The weight of the load and the weight of B are fairly at the same side.. (beyond the midpoint of the bar). The implication of this setup is that, the complex of B and the load would instigate a clockwise moment.

A direct consequence of this is that the bar at A would tend to be lifted up.. To prevent this from happening, Mr. A must send a force of the same magnitude as the weight of B and the load put together...this force must act in an opposite direction to the line of action of the weights of B and the load. This force would make up the anti-clockwise moment.

In conclusion, A is exerting a force equal to the weights of B and the load put together. Therefor, A is doing a greater work.

YOUR ANALYSIS IS TRUE IF THERE WAS SOME SORT OF SUPPORT AT THE MIDPOINT(which is not stated) THUS NO MOMENT ABOUT YOUR SO-CALLED MIDPOINT. MIND YOU, THE ROD CONTINUES TO THE RIGHT AFTER MANB.

Joe82834:
Well u can look at it from this angle. Both A and B are applying vertical upward forces so d one with d greater force should b d one bearing most of d grunt.

Assume distance from A to load is P n distance from B to load is Q(bearing in mind dat P is greater than Q). We can use d principle of moments about d given load.clockwise moment shd equal anticlockwise moment.
F_A × P. = F_B × Q
F_A = (Q/P) × F_B
Now since P is greater than Q it can b said that the force exerted at A is less than that at B

Joe's just thinking

I STRONGLY DISAGREE WITH YOU SIR AS THERE IS NO POSSIBLE AXIS OF ROTATION AT THE POINT OF APPLICATION OF THE LOAD.



To solve this problem, we must make two simplifications:
1.) The rod is uniform and massless(we lack information on its length)
2.) The rod rests on the shoulders of man A and B as though there is a knife edge placed there.

Obviously, the system(rod) is at equilibrium and we apply both conditions for equilibrium... Fnet =0 & Torque°net=0...
let the weight of the load be "W", man A and B provides reaction forces "Fa" and "Fb" respectively. let distance from manA to ManB be "x", distance from manA to load be "y" thus distance from load to manB is "(x-y)"...


since Fnet= 0,
Fa + Fb = W....(*)
since Torque -net = 0,
we consider torque about manB,
Fa*x = W×(x-y) ---(**)
we consider torque about manA,
Fb*x = W×y ---(***)
Note: Fb produces no Torque as its line of action passes through the axis of rotation in (**) likewise Fa in(***).

from(**),
Fa = [(x-y)/x]×W ... (I)
from(***),
Fb = [y/x]×W ....(II)

from figure in the problem, it is obvious that y>(x-y),
in view of (I) and (II), we can safely conclude that Fb > Fa. This means manB is carrying a heavier load.

Na wa oo... some people sabi English pass The English people wey create the language sef.

Brother you're not absolutely correct (in fact very wrong) because in palindromes, you don't "mirror" the letters, instead you repeat the letters in reverse order.

Take POOP as a palindrome for example, "P" is not written as "9" you know.

Some people are not looking for the "beauty of form" but always trying to correct other peoples use of English like it is their mother tongue. Shiorr...!

Next time use a dictionary.

"RISE TO VOTE SIR", is also a Palindrome.

I see... if "RISE TO VOTE" is also a palindrome, then the Op is wrong to say the sentence he gave is the only English palindrome.

"r" equally follows this principle.

this is false. the "C" in CAR and CAT when read in reverse would not be written C correctly.

Here is my proof

take for instance the sentence was written with a marker on a Car windscreen from outside, an observer inside the car rather than seeing a CONCAVE 'C' will see a CONVEX 'C' hence, there is no Symmetry in this sentence as claimed by the OP.

The Structure will stand the test of time if
1.) the depth of the glazed ceiling is not too much cause then, the density of Ocean water which is about 1024kg/m³ would imply an increase in mass of water above the ceiling cause volume has increased. this in turn will depend on the compressibility, sheer and Young modulus of the glass material. If these factors are considered, the project would be a successful one.

AB Mico. dept of Building , OAU.

few days back, someone asked me

" I am a 20 year old boy. I don't have any girlfriend
and I want to find a nice girl, say between 18
and 45 years of age, from the United States of
America or another American country. So what
should I do to find her?"

well, I believe many young Nigerians think like this boy. If you're like this boy well, here is what I have to say;


Let me first warn you, there are a number of
young men in the same situation as you. Your
desire for a future wife in another country is
both hard to accomplish and leaves you
vulnerable to scams. There are a number of
people who are eager to take your money and
make you promises they will never fulfill.
The purpose of having a girlfriend is to find
someone who will be your companion and friend
for the rest of your life. This means you need to
met people to get to know them and they to get
to know you. That is hard when you are in one
country and they are in another country. It can
be extra hard if you have trouble conversing in
each other's languages. While the Internet
makes it very easy to talk to people all around
the world, the Internet makes it far too easy to
pretend. A lot of people are not who they claim
to be and since you can't see them, you can't
tell when someone is lying to you.
The best way to meet someone is to go places
where you have interests because other people
with the same interests will go to those same
places. If you want to met Americans and can
afford to go to one of the American countries for
visits, then find out where visitors come to see
your country. If you can, get a job that puts you
in contact with people visiting, such as a tour
guide. Such jobs will also force you to improve
your language skills.
Whether you find a girl locally or elsewhere, you
need to also consider what you offer the
relationship. Do you have a good job that allows
you to support a family? Do you prove to be a
hard worker? Do people know you to be honest
and caring? In other words, think about yourself
from a woman's viewpoint and ask yourself what
you can do to make yourself a better man whom
a woman would want to marry. If you have no
ideas, ask your mother or some other women
you know for suggestions on how to improve
yourself to be good husband material.
In your eagerness, never rush a relationship. Get
to know the other person well and let that
person get to know you well. It is when you rush
that you make mistakes.
Finally, be yourself. Too many young men, in
their eagerness to find a wife, pretend to be
someone they are not. It makes them look
artificial and unattractive. But even if you do
find a woman who falls in love for whom you
pretend to be, what happens when she finds out
the truth? I know you want to impress a woman,
but impress her with your actual good qualities.

for more info, contact 09093004542 so I could add u up to the whatsapp grp consisting of young Nigerians and Americans. Ladies too might find themselves soulmates in the group.

sorry that you have small pepeye idiat

lol...I like u

Let x = 0 be the solution to an equation Eg in 5x = 0 Divide both sides by 5... 5x/5=0/5 X = 0 DIVIDE BOTH SIDES BY x... x/x = 0/x _____________ | 1 = 0..... Don't you think something is wrong? NO... My theory.... Think of binary numbers... Now think of scalers... In binary, 1 reps TRUTH and 0 reps FALSE... I just proved that what we consider to be the TRUTH might be False! In fact I conclude Life is just an illusion since we're not even sure of the truthfulness of who we are. Signed - ABOLARIN L.M...09093004542.



please share to encourage me make other incredible findings.

and I don't think I deserve those words from u

petkruz:
Dude don't mention my name again! I believe it's not by force to reply u right? I saw your previous comment where u called your generation a bitch,i ignored u and now u mentioning my name a second time,what the hell is wrong with you? Is it by force to comment on a thread? I can be very very disrespectful so please respect yourself.

I never called u a Dam

why is this a big deal guys? its obvious petkruz is suffering from a condition Adolescent girls go through. they model a popular icon as an ideal boyfriend/husband. That's why they're usually choosy. The usually end up with dudes that are not in anyway like their model when they are much more older.

see small pepeye oooo


I pity him oo, fine guy like this, or are you sure its not arrow from his village
