alleryA loaded body that does not regain its original dimension after the load is removed is said to have what?
AA yield strength
BA permanent set
CA lateral strain
DA bulk modulus
Answer & Solution
Correct answer: B. A permanent set
1. Beyond the yield point the strain grows fast for little extra stress.
2. When the stress is brought back to zero the strain does not return to zero.
3. The material is said to have a permanent set.
