Transcribed Image Text:Suspend the meter stick on a pin through the hole at the 25 cm mark. Add weights on the string at the
0m end of the meter stick to balance the stick (the stick should be horizontal).
Calculate:
a. Fpin (magnitude and direction), using F =0
b. The sum of the cw and the sum of the ccw torques about point 0 (pin). Since the stick is in
equilibrium, these sums should be equal.
c. Calculate the % difference between torques: 7r and reow"
The % difference indicates how far the experiment departs from the ideal, and therefore is a
fair indication of the experimental error.
% Diff = 2 -2 100%
