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 1200 g and 900 g respectively.
