Levers and Balance
Levers and Balance

In the first lab, students will investigate the arrangements of weights that result in equilibrium (balance) in the lever system. They will find that both the force and the distance from the fulcrum are important in evaluating the system. This...

Equilibrium and Torque
Equilibrium and Torque

This lab has two activities. In the first, students investigate the arrangement of masses on a center-pivot lever required to produce balance. They will develop the idea that both force and lever arm produce torque, and that both quantities must...

Lab # 2.1   Mechanics:  Walking the Plank
Lab # 2.1 Mechanics: Walking the Plank

Purpose In this activity, students will measure and interpret the forces acting on an object when the object is in equilibrium. Discussion Consider two sign painters who work on a scaffold (a plank of wood suspended by ropes at both...
