Answer:
C) Longitudinal and shear
Explanation:
According to the question the spring is stretched by applying a load on a free end, thus the spring is also suspended with a fixed rigid support. Since, the load is attached with the lower end of that spring, therefore it is stretched by applying a load to its free end. Upon the stretch the length and shape of the spring changes and the weight of the load behaves as a deforming force.
The overall change in length of the spring corresponds to the longitudinal strain and change in shape corresponds to the shearing strain.
