Published on 07/30/2010

Activity Overview

Students explore the conditions necessary to produce static equilibrium in a first-class lever.

Key Steps

  • Image

    Students use a precompiled data set to explore the relationship between force, torque, and lever arm.

    Next, they examine the data on effort arm and effort force.

    Finally, they use the collected data to calculate the effort torque. They compare the effort torque with the resistance torque and confirm that balanced torques produce no rotational acceleration.
