1. Place the meter stick on the vertex of a triangular wooden block so that it balances horizontally. Determine the point of balance of the stick. This is its center of gravity. 2. To determine the weights of the 2 unknown masses by torque, hang the masses from the meter stick such that the lighter mass (with weight W1) is at 1 cm mark and the other mass (with weight W2) is at a point where the stick balances horizontally. Note the position of W2. Write a torque equation of the system.
