8. Where would a fulcrum have to be placed in order to balance a 65.0g meter stick (center of mass = 50.0cm) that has a 30.0g mass attached at the 12.0cm mark and a 60.0g mass attached at the 92.0cm mark?

Answer #1

Assume a position for the fulcrum from the left end and the torque about that fulcrum due to all the three weights will be zero. We use this condition to find the required distance as shown below

2. Does the fulcrum contribute any torque to the system? Does the weight of the meter stick contribute and torque to the system? If the fulcrum were shifted past the center of mass of the meter stick, say, to the right, would the fulcrum then exert a torque about a point of contact between it and the meter stick? Would the weight of the meter stick exert a torque about that same point?
