For the demonstration of Hooke's Law that the elongation produced in a spring within elastic limits is proportional to the load applied to it. Also useful for investigating potential energy and investigating masses. Comprises of a metal rod carrying vertically a polished stainless steel scale 0 to 15 CM, with provision for its height adjustment. An integrated mass hanger/pointer is connected to the lower end of the spring with the eye shaped upper end for suspension through an adjustable collar with cross bar, which is positioned above the scale. Complete apparatus mounted on a stable base.
