Question

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

• A. $\alpha \Delta \theta$
• B. $\frac{1}{2}\alpha \Delta \theta$
• C. Zero
• D. Information incomplete

Answer 1

Answer: (C)

Zero

Answer is C.

Here rod is free to expand from one side so by changing temperature no strain will be produced in the rod,and rod will free elongate .
