Question: The modulus of resilience is defined as:

Options:

1. The energy per unit volume stored in a material up to the yield point
2. The total energy absorbed by a material before fracture
3. The ratio of stress to strain
4. The maximum stress a material can withstand

Correct Answer: The energy per unit volume stored in a material up to the yield point

Solution:

The modulus of resilience is the energy per unit volume stored in a material up to the yield point.
