Resilience of a bolt can be increased by increasing its __________________?
Correct answer: A. Length
- A. Length
- B. Shank diameter
- C. Head diameter
- D. None of these
Explanation
For a bolt under a given load, elastic strain energy varies directly with its length, so increasing length increases resilience. Increasing shank diameter makes the bolt stiffer and reduces the stored energy for the same load.
