Take four springs, two of the same length and the remaining two of the same and radius. Make arrangements for measurement, a laboratory stand with clamp, a hanger, a metre scale and a weight box with a set of varying weights. Support the spring, one at a time vertically from the laboratory same. Add a muscle weight at the bottom of the hanger. Measure the extent on the metre scale attached to the spring. Take 6-7 readings by gradually increasing the weight on the hanger. In each spring, draw a graph between the load suspended from the hanger at the exterior of the spring. Write your results in the form of a table and properly interpret them. This project has application in spring balance.
