- The twisting of an object due to an applied torque is called as torsion or twisting moment.
- Rotational motion about longitudinal axis is produced when a member is subjected to couple.
- For shafts of uniform cross-section, the formula used to calculate torsion is
The relation ( T/J = Gθ/L = τ/ R) is called as torsion formula.
Here,
T is the twisting moment
J is the polar moment of inertia
G is the modulus of rigidity
θ is the angle of twist (radian)
τ is the shear stress
R is the shaft radius
