Objective

The purpose of this experiment was to help understand torque by not only measuring it but also by manipulating and adjusting the weights experimentally.

Procedure

In order to perform all the procedures a few instruments were required a meter stick, a triple beam balance, suspension clamps and their stirrups, a knife edge, as well as weights of 50 and 100 grams and a spring scale. The meter stick was weighed (without the clamp), and its center of gravity was found (it's not usually exactly at 50cm), the 6 clamps were weighed as well. For the first part the meter stick was put on 35cm and a 100g weight was adjusted until the center of balance was found, the position was recorded, this was than done with 150g and 50g. Once the values were recorded the weight of the bar was calculated and the average was found. For the next part of the experiment three weights were attached anywhere on the bar, the center one was adjusted till there was equilibrium and than the force was measured
