PR-64
It consists of a metal base board, hinged at one end supporting a scaled planed board.
Dimensions of the inclined plane=60 x 7.5cm.
The planed section can be inclined and fixed at any angle from 0-45° to the horizontal measured on the attached angle measurer.
The end of the inclined board features an adjustable aluminium pulley wheel from which masses can be suspended.
Diameter of pulley= 38mm.
A scale pan and a cylindrical metal roller are included.
Weights can be bought separately.
This is a classic example of a simple machine and helps students to understand how an inclined plane makes work easier.
It is used for investigating forces acting on a body on an inclined plane, and determining the holding friction as a function of the angle of inclination.
