Show hintHide hint
Think about the implications of length change.
3Question 3.
What is the formula for calculating longitudinal strain?
- ΔL/L
- F/A

4Question 4.
True or False: Longitudinal strain can only be positive.
- True
- False
Show hintHide hint
Think about what happens when materials shorten.
Question 5.
A cylindrical rod of length 1 m and diameter 10 mm is subjected to a tensile load causing it to stretch 2 mm. Calculate the longitudinal strain and discuss its implications for material selection.
Show hintHide hint
Focus on the ratio of changes in the length of the rod to its original length.
Question 6.
In a beam under a distributed load, show how to calculate the local strain at various points along its length as it bends.
Show hintHide hint
Express the problem in terms of physical properties like Young's modulus and the dimensions of the beam.
