In the question rumber 66, for what value of `theta`, shearing stress is maximum?

A

`0^(@)`

B

`30^(@)`

C

`45^(@)`

D

`90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
Shearing stress `=(F sin 2theta)/(2A)`
Shearing stress is maximum when `sin 2theta =1`
`or Sin 2theta = sin 90^(@) or 2theta = 90^(@)`
` or theta = 45^(@)`
