Please explain the torsion equation?
Answer:
The torsional equation is, T/J = q/r = GӨ/L
Where,
T – Torsional moment (T is in N-mm)
J - Polar moment of inertia (J is in mm⁴)
q – Shear stress in the element (q is in N/mm²)
r - Distance of element from centre of shaft (r is in mm)
G- Modulus of Rigidity (G is in N/mm²)
Ө – Angle of twist (Ө is in radians)
L – Length of the shaft (L is in mm)
