Angular Deflection of Solid Cylinder or Shaft with Torsion Applied
The angular deflection of a solid cylinder with torsion loading applied:
θ = L T / (G J )
Open Torsional Deflection of Shaft Calculator
Where:
θ = angular shaft deflection (radians)
T = torque (N-mm, in-lb)
L = length of shaft (mm, in)
G = modulus of rigidity (Mpa, psi)
J
= Polar moment of inertia (mm4, in4)
#2 Equation and Calcuator for Angular Deflection of Solid Cylinder or Shaft with Torsion Applied
θ = 32 L T / (G π D4)
The angle in degrees can be achieved by multiplying the angle θ in radians with 180/π
Solid shaft (π substituted)
θdegrees ≈ 584 L T / (G D4)
