B2-03: EQUILIBRIUM OF FORCES - INCLINED PLANE

PURPOSE: To demonstrate equilibrium of forces.

DESCRIPTION: 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

SUGGESTIONS:

REFERENCES: (PIRA unknown.)

EQUIPMENT: Inclined plane with pulley, cart, 200g, 100g, 2 50g, and 20g masses, as photographed.

SETUP TIME: 5 min.
