Question

For this lab, all applied forces will be vertical at 90 sucn that the lever arm will be the kor horizontal distance from the force to the pivot point. 10 Uniform Meter stick Hanging Mass Set Fulcrum Clips and Hangers Triple Beam Balance Equipment: Pre Lab Question: 1- What is torque 2- If torque is not zero what can you say about motion of object? 3- If you increase distance respect to axis of rotation then the force will be decrease or increase, explain Procedure: Part I: Center of mass of a meter stick Support the meter stick with its sliding 'knife-edge' attachment on the metal stand. Slide the stick through the knife-edge until it balances. Clamp the knife-edge to the meter stick and it there for the rest of the lab. The center of mass is at the knife-edge. Record the meter meter leave stick reading at this point. Center of mass for meter stick (m): 2

Explanation / Answer

1. Moment of force is called torque i.e., product of force and perpendicular distance from axis of rotation.

2. If torque is not zero, the body executes rotatory motion about the axis of rotation.

3. If the distance from axis of rotation is increased, force does not change but moment of force will increase.
