PHY 181. conduct an experiment B1.
Title: Measurements with Calipers, Screw gauge, Stopwatch, and Estimation of errors

1. use the calipers to measure the breadth, b and thickness k of the meter rule at ten different points and record your readings neatly.
2. use the screw gauge to measure the diameter, d of the wire at ten different points and orientations. And use the meter rule to measure the length, l of the wire ten times.
3. set up a simple pendulum of length 50cm and determine its periodic time, T by timing 10 complete oscillations (ten times)
