Question

When a structural member is strained due to external imposed loads, the energy stored is called -

• A. Yield point
• B. Strain energy
• C. Elastic limit
• D. Endurance limit

Answer 1

Answer:

B. Strain energy

When a structural member is strained due to external loads, the energy stored in it is called strain energy. It is a type of potential energy that is stored in the member due to elastic deformation. The formula for strain energy is $U = \frac{P ^ 2 L}{2AE}$
