Torsional Deformation and Stress Hollow Rectangle Thin Wall Tube Section Calculator Angle of Twist under applied Torque Moment

θ = ( T L ) / ( K G )

Shear Stress

Near the mid length of the short sides Near the mid length of the Long sides Where:

θ = angle of twist (radians)
α = degrees
T = Twisting or torque moment force-length, (in-lbs, N-mm)
L = Length (in, mm)
a, b = Diameter (in, mm)
t = Thickness wall (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
