Work Done By A Variable Force

The equipment consists of a pivoted arm carrying a weight at its end and kept in equilibrium by a spring balance at right angles to the arm by holding the free end of the spring balance on the angular position of the arm is indicated by an angular scale the arm pivot.
Work Done By A Variable Force (Tangential Effort) : This apparatus is for demonstration of work done by a force as area under the graph of force and the distance it moves.

Features:
Reinforces concepts of work and energy
Direct reading of tangential effort
Low cost, effective teaching
Self-contained
Bench mounted.
