Very nice

khiaa:
Yeah, I've been quite busy.

Ok, happy to have you back

khiaa:
Happy Holidays.

Khiaa, thank you.

Longest time

Structural Engineer....
Graduated this year...
School : Futo...

Hope we learn one or two from this thread

Is that the laffin gas that graduated from Futo?.....

That guy don dey go far.... very funny guy

Dramadiddy:
naa I beg to disagree.. SAAT has hot chics, SOHT, SMAT has fine girls too.. I believe that's an old pic.. Now? You need to see things for urself

Guy, that babe is a futoite from SMAT. She even did pre degree in Futo. Believe it or leave it.

Dramadiddy:
bro we got new faculties with high influx of "beautiful" girls. Op is just angry cos they no answer am. Futo girls got class

Class fire......though na for SOSC you go see fine girls


The funny part is that the girl is actually a Futo girl. She's a course rep/assistant course rep in SMAT.

Op, you are not far from the truth. We Futo graduates know better.

Congratulations to Miss Anambra....


Though I am not happy that my Miss Bauchi lost it..... that babe is innocently beautiful with her sweet seducing smile

Please oo, is Willie Obiano a professor?....

Miss Anambra called him Professor Willie Obiano

Correct me if I am wrong here oo, just curious

Chai!!... Come see as my elder bros and I dey trip for Miss Bauchi


That babe fine

I know Christ the King College, Onitsha (CKC) will make the list (5th position) .

Proudly bonitas, disciplina and Scientia.

@TheSuperNerd, I am virtually through with my first degree in civil engineering and by God's grace, I should be graduating with a first whenever the final result is released. The major dilemma I am in right now is should I proceed with my academic pursuit in a foreign university(provided I could secure a scholarship) or seek employment in an engineering firm?
I would be grateful if you could recommend some very good scholarship schemes I may apply for during my NYSC. Thanks in anticipation.

You are not alone, dude. Also looking for good scholarship schemes for my masters. Though I just graduated(civil (Structural engineering)) , but I wish to run my masters in another field probably "Offshore engineering ".

This nuella is what they call a Husband Snatcher

This got me laughing...lolz

Carry everything to God in prayers. Maybe it's not natural.

Timi Dakolo rocks. "Wish me well"

When I heard the song first, I kept on repeating it...

Wherever I play it, people love it and demand I should send the song to them.

With Barcelona I have peace of mind.

Roma 1-3 Barcelona

Messi = 2 goals
Suarez = 1 goal

God bless all barca fans

Nice piece

distinguished1:
why didn't u use Laplace transform to evaluate it. Anyway, bravo!

Lolzz....In my third year I just love everything about that man after doing one course like that (Engineering mathematics)

Using Combination (C) in mathematics ...
Let the number of handshakes be X

XC2 (X combination 2) = X! / (X-2)! 2! = 120

X! = (X-2)! 2*1*120
X! = 240 (X-2)!
X * (X-1) * (X-2)! = 240* (X-2)!

(X-2)! Will cancel each other on both sides
So we have;

X * (X-1) = 240

X^2 - X = 240. ( solve the quadratic equation)

X = 16 or X = -15...

X can never be negative value, so

X =16

11 * 11 = 4^1 = 4
22 * 22 = 4^2 = 4*4 = 16
33 * 33 = 4^3 = 4*4*4 = 64

I feel blessed to be educated once again by your comment. Satisfied!
Hey, any test for me as per the subject matter...from you as a teacher?

Lolzz.... Oga mi, I don't think there is any need for an online based test for you, but when you interact with people outside nairaland always make sure you use the right Personal pronouns for the two modal auxiliary verbs (Shall and Will). It's all about scrutinising your sentences before you speak them out... Na the method me sef dey use,cos English no be our mother's tongue

Let me contribute a little that I know about the two words...

Shall and will are both modal auxiliary verbs used to talk about a future event or an action expected to take place at a time in future.

However, SHALL is used with the first person personal pronouns "I and We" to suggest a future event... eg
(1) We shall travel next month.
(2) I shall visit you next week.

WILL on the other hand is used with the second and third person personal pronouns such as "She, They, He, It, You, etc" to also suggest a future event... eg
(1) He will travel next month.
(2) They will visit you next week.
(3) It will rain tomorrow.

However, when the sentence is attached with a special meaning such as (A) Promise (B) Threat (C) Command, etc, then "SHALL" goes with the second and third person pronouns respectively, whereas "WILL" goes with the first person pronouns....Eg

(1) You SHALL obey your parents. (Command).

(2) I WILL show you how wicked I am. (Threat).

(3) Ifeoluwasegun SHALL receive one like from me if his topic makes front page. (Promise).

Lolzz..... permit me to stop here...

abdulwastecx:
please can i have a copy of your thesis ?

Ok sir, but that will be after my project defence...

engrjacuzzi:
how do I calculate the bending moment and fixed end moment of this building?

Lolz... use Moment-Distribution Method by Hardy Cross. shebi na 5-storey building?...you go spend weeks doing the analysis .


On a serious note, engineers should learn how to use softwares to run their design and analysis, coupled with including wind load analysis for buildings exceeding 4 floors. They should also use theoretical methods to determine the bearing capacity of the soil for such superstructure and give it a reasonable factor of safety since carrying out in-situ tests like SPT, CPT,etc are very expensive .It's all about safety.

Hope no life was lost.

abdulwastecx:
thank you for that arithmetic correction my brother.

with regards to the quantity of constituents materials, I am of the opinion that their respective density is the major determinant of their quantity in cement. For example, for a cubic of concrete when wet, the only material that is lost after setting and hydration process are water, void and to some extent heat ( this doesn't occupy much space). this materials especially water are also constituents and their weight need to be determine prior to mixing.

concrete tense to shrink after setting ( harden) due to loss of moisture (water) content using the relative density of concrete will not give us a through reflection of the quantity of the constituent materials.

Assuming we want to produce one cubic meter of concrete using 1:2:4
a volume of concrete will have the followings constituents
1. 1/7x 1 = 0.143m3 of cement

2. 2/7x2 = 0.286m3 of sand

3. 1-0.143-0.286 = 0.571m3 of gravel

4. 0.55x143= 77liters of water

small increase of 25% can then be allowed to cater for increase in volume due to shrinkage and poor handling of concrete.

since it will be impossible to go to the market and get these materials in unit such as m3, you will need to convert them to unit understood by trade men. Language such as bags, tonnes and liters comes to mind.

to convert the quantity of cement in volume to weight you need to know the density of THAT MATERIAL because of the relationship between them is: density = mass/volume

thus; cement requires becomes = 0.143 x 1506/50 = 5bags (aprox)
sand is been sold in tonnes, quantity of sand = 0.286x1.6 = 0.5tonnes (aprox)
gravel also comes in tonnes, quantity of gravel =0.571 x 2.4 = 1.5tonnes of gravel (aprox)

note where, 1506kg/m3, 1600/1000(tonne), and 2400/1000(tonne) are the density of cement, sand, and gravel respectively

Sir Abdul, thanks for taking your time to type this.. it's becoming interesting and believe me, the reason why I want both of us to tackle this is because you are a first class brain..... now to the matter, One thing I understand about your own method of using different densities of cement, sand, and gravel is that it works best for Standard mixes (1:2:4, 1:3:6,etc) due to incorporation of 25% for wastage and shrinkage .

I recently carried out a final year project with a design mix of 1: 1.38 :2.35 for a target strength of 38.20N/mm2 for 12 cube moulds, 12 beam moulds and 12 cylindrical moulds with total volume of 0.26614m3...
Now, using the density of cement gave me a number of 1.69 bags (approximately 2 bags of cement).... Also, using the "wet density of concrete of 2410kg/m3" which I got from my design mix gave me a number of 2.71 bags (approximately 3 bags)..... now after carrying out this project of mine I used about 2.8 of the 3.0 bags I bought...

Again, using different densities of cement, sand and gravel for a mix ratio of 1:2:4 will alter the mix ratio to 1:2:6 from your calculation which goes thus :

Cement(5bags):sand(0.5ton):gravel(1.5ton)
250kg : 500kg : 1500kg
1 : 2 : 6

since the 1:2:4 is a STANDARD MIX (which the labourers will work with as 1 bag of cement, 4 head pans of sand and 8 head pans of gravel) it won't be affected, but when it's a DESIGN MIX it will be greatly affected thus reducing the compressive strength.
I have compared the two methods (ie using different densities of the constituents and the wet density of concrete) using a 150 x 150 x 150mm cube, cured for 28 days and crushed in the laboratory using a compressive testing machine and that of "wet density of concrete " gave the desired strength.

I know you will be too busy now to try this and compare..

Oga Abdul..... you are always on point. In fact, I don learn many things from you and I am willing to learn more....just that my phone bin crash so I no come follow this post on time.

Please eeh, check that ELEMENT 3... sum of mix ratio is 10 (1:3:6),I know you mistakenly used 9... Also, when determining the Number of bags of cement, tonnes of sand and gravel, I think what we should be multiplying with should be the "wet density of concrete " which ranges from 2400-2500kg/m3(Generally, most people use 2400) depending on the mix ratio and the characteristic strength of the concrete and not the density of the materials(cement, sand, gravel)... Please, check it out and give me feedback,cos I will really appreciate . A layman in Civil Engineering may not understand my point, but as a guru you are am sure you gonna understand.

Lolz.... it feels good to be a FUTO student... proud.
