A rod is made of uniform material and has non-uniform cross section. It is fixed at both the ends as shown and heated at mid-section. Which of the following are not correct?

A

Force of compression in the rod will be maximum at mid-section.

B

Compressive stress in the rod will be maximum at left end.

C

Since rod is fixed at both the ends, its length will remain unchanged. Hence, no strain will be induced in it.

D

Force of compression is the same throughout the rod.

Text Solution

Verified by Experts

The correct Answer is:
A, C
As force of compression is same throughout the rod, due to static equilibrium, compressive stres s will be maximum at the left end, least at the right end.
