Question

Collect two springs of different thickness.
(i) Cut a piece of 15cm of each spring.
(ii) Arrange a laboratory stand with clamp, a weight box and a set of weights.
(iii) Suspend one of the springs from the laboratory stand.
(iv) Fix a 15cm scale parallel to the hanging spring so that the zero of the scale is near the lower end of the spring.
v) Using trial, find which ranges of weights produce measurable extension in the string with the condition that each time, the weight is removed, the spring attains its original length. (Think ! Why this condition?).
