Amanda Runey PHY111 Segvich 8 April 2008 Equilibrium/Torque and Hooke’s Law Labs Introduction Torque is the rotational counterpart to a linear force. If a force is applied over some lever arm the object will rotate. Equilibrium is the state at which the net forces and net torque applied to an object are zero. The first lab sought to apply different forces to an object and balance the torques about the pivot point producing a system in equilibrium. Hooke’s law states that the amount of stretch, or change in length, is directly proportional to the force applied. If the force is decreased then the stretch should also decrease. This is called the spring constant of a spring. The second lab sought to investigate Hooke’s law and find the spring constant of the spring we used. Procedures/Methods For the torque lab we set up the meter stick to balance on the fulcrum without any masses on either side. Then we added a weight on a hanger to one side and calculated where on the other side of the fulcrum a known mass would have to be placed in order to create equilibrium. We repeated this several times using different masses and distances. Finally we placed a weight with a hanger on one side of the meter stick and made the meter stick balance. For Hooke’s law and the spring constant we set up the apparatus with the pointer
