Jeff Trask 9/18/2007 Section A PHY 110 Lab 3: Torque Purpose: The purpose of this lab is to gain an understanding of how force, distance, and the center of mass of an object relate to the topic of torque. Abstract: In order to demonstrate how the force and distance interact to form a torque, a meter stick was placed with its center of gravity on a pivot and different weights were added to each side, then put into equilibrium by adjustments of their distance from the center of mass. The pivot point was then moved, which added the weight force of the meter stick itself into the equation, because the force of an object is assumed to originate from the center of mass. In order to find the torques, the equation τ = F x d is used, which states that the torque equals the force (in this case the weight force of the various objects, or the mass of said objects times 9.8 m/s 2 ) times the distance ( d ) the object is from the pivot point. Torque is measured in Newton meters (Nm) because it is a
