Question
Chapter 18, Problem 13A
To determine
To Explain: Whether Steel beam is slightly shorter or not when it stands vertically.
Expert Solution & Answer
Explanation of Solution
Introduction:
Steel is an elastic material. By property of elasticity, it can be stretched or compressed.
When no load is applied on a vertical steel beam, there is no compression of the beam. When load is applied, the steel beam gets slightly compressed. Steel beam stands slightly shorter when it stands vertically.
Conclusion:
When vertical steel beam is under load, it is slightly shorter.
