APPARATUS HOOKES LAW

Demonstrates the correlation between the elongation produced in a simple spring and the load applied. Can also be used to demonstrate harmonic motion by counting the oscillations per selected time period of a vibrating weight suspended from a spring. Adjustable vertical metal rod supported on a graduated steel scale. Spring is suspended through a cross-bar by means of a collar and has a mass hanger at its lower end. Loading the mass hanger with masses produces extension in the spring, which is indicated by the pointer against the scale.
