Additional Info

• ID Code: B2-03
• Purpose: Demonstrate equilibrium of forces
• Description:

  Place the box on the inclined plane with a mass in it, and let the students see it slide down the slope. Challenge them to predict the mass that is needed to hang off the end in order to keep the box stationary.

  Given an angle of inclination a of the inclined plane, this apparatus demonstrates that the mass m required to hold a cart of mass M at equilibrium on the inclined plane is given by:

  mg = Mg sin a
