Question

In an element of a stressed body is under the state of pure shear of 60 N/mm\(^2\), the magnitude of maximum principal stress at that location is

• A. 30 N/mm\(^2\)
• B. 60 N/mm\(^2\)
• C. 90 N/mm\(^2\)
• D. 120 N/mm\(^2\)

Hint:

For pure shear stress conditions, the maximum principal stress is the same as the shear stress magnitude.

Answer 1

The Correct Option is B

In a body under pure shear, the maximum principal stress is equal to the shear stress magnitude. Hence, the magnitude of the maximum principal stress is 60 N/mm\(^2\). Thus, the correct answer is 60 N/mm\(^2\).
