θ = T L / K G

Polar Moment of Inertia

Shear Stress

τ = T / Q

Angle α

α = cot [ b / (a/2) ]

Where:

θ = angle of twist (radians)
α = degrees
T = Twisting or torque moment force-length, (in-lbs, N-mm)
L = Length (in, mm)
a = Distance as indicated (in, mm)
τ = Unit shear stress force / area (lbs/in2, N/mm2)
G = Modulus of rigidity force / area (lbs/in2, N/mm2)
K = Polar Moment of Inertia (in4, mm4) for section
Q = Polar Moment of Inertia (in4, mm4) for section
