A circular bar of diameter 30 mm is subjected to an axial force of 40 kN and a torque (CW) of 500 N-m at one end while the other end is fixed. Then using Mohr’s circle
1
The radius of Mohr’s circle will be 98.45 MPa
2
The angle of the maximum shear plane is 81.65°
3
At a plane of 60° with the bar axis, the normal stress will be 95.81 MPa
4
The angle of principal plane will be 36.6°
