Question
A spring is stretched by applying a load to its free end. The strain produced in the spring is ______.
Options
volumetric.
shear.
longitudinal and shear.
longitudinal.
Solution
A spring is stretched by applying a load to its free end. The strain produced in the spring is longitudinal and shear.
Explanation:
According to the diagram where spring is suspended with fixed rigid support. Now a load is attached to the lower end of that spring. So, it is stretched by applying a load to its free end. Clearly, the length and shape of the spring change and the weight of the load behaves as a deforming force.
The change in length corresponds to longitudinal strain and the change in shape corresponds to shearing strain.
