Instructions / Notes:

• The sides of the triangle are in the ratio of 3:4:5.

• The 1500 g block rests on a stop which can be removed after the force parallel to the incline is balanced.

• Slide the incline out of the way after the force perpendicular to the incline is balanced. The block will be suspended.

• The masses to balance the perpendicular and parallel forces are 910 g and 1210 g respectively.
