railway RRB JE (CBT I + CBT II) Mock Test 2024 Strength of Materials Torsion of Shaft Effect on Shaft
Maximum shear stress developed on the surface of a solid circular shaft under pure torsion is 160 MPa. If the shaft diameter is doubled, then the maximum shear stress developed corresponding to the same torque will be:
1
10 MPa
2
30 MPa
3
40 MPa
4
20 MPa
