railway RRB JE (CBT I + CBT II) Mock Test 2024 Strength of Materials Torsion of Shaft Effect on Shaft
Torsional stiffness is defined as
1
torque required to produce a twist of one radian over the length of the shaft
2
torque required to produce a twist of one radian per unit length of the shaft
3
torque required to produce a twist of one radian per unit cross sectional area of the shaft
4
torque required to produce a twist of one radian per unit modulus of the shaft
