In the given figure, a rod is free at one end and other end is fixed. When we change the temperature of rod by `Deltatheta`, then strain produced in the rod will be

A

`alphaDeltatheta`

B

`(1)/(2)alphaDeltatheta`

C

zero

D

information incomplete

Text Solution

Verified by Experts

The correct Answer is:
C
Here rod is free to expand from one side. So by changing temperature no strain will be produced in the rod, Hence answer is (c ).
