ISRO Mechanical & Aerospace 2011 - Question 48

All ISRO Mechanical & Aerospace papers | ISRO Mechanical & Aerospace 2011

For the state of stress shown in the figure (Pure Shear $\tau$?), normal stress acting on the plane of maximum shear stress is

Figure for question 48, ISRO Mechanical & Aerospace 2011

  • A. 25 MPa tension
  • B. 75 MPa compression
  • C. 25 MPa compression
  • D. 75 MPa tension

Answer: A. 25 MPa tension

Explanation: Based on the ISRO solution for this problem (typically includes diagram), the normal stress on the max shear plane is the center of Mohr's circle: $(\sigma_x + \sigma_y)/2$.
