Hint: This problem is based on the Mechanical properties of solids, we know that Stress and Strain play a significant role in establishing a relationship between different parameters hence, analyze each & every option given with the scientific approach and check which option seems to be more appropriate for the given situation to present the answer with proper explanation.
Complete answer:
When spring is directly stretched by suspending a load, a downward force $'mg'$ will act upon it due to the load being suspended. In this case, the stress produced in the spring will be transverse stress, and as a result of which there will be an extension in the spring.
This transverse stress produced in the spring can be evaluated with the help of the Modulus of Elasticity or sometimes it is called, the modulus of Transverse Elasticity.
Due to this transverse stress, the strain developed in the spring is called “Shearing Strain”.
Thus, when a spiral spring is stretched by suspending a load on it, the strain produced is called Shearing Strain.
Hence, the correct option is (A) Shearing.
Note: Since this is a multiple-choice question (theory-based), it is essential that given options are analyzed carefully to give a precise explanation. While writing an explanation for this kind of conceptual problem, always keep in mind to provide the exact reasons in support of your explanation.
