K = 2Cr4

Varies with b / r as follows

For:

0   ≤   b / r ≤   0.5

Where 0.2  ≤   a / b   ≤   1.4

Angle of Twist under applied Torque Moment

θ = ( T L ) / ( K G )

Shear Stress Maximum

At M:

Where B varies with b / r as follows:

for 0 ≤ b / r ≤ 0.5

for 0.2 ≤ a / b ≤ 1.4

Where:

θ = angle of twist (radians),
T = Twisting or torque moment force-length, (in-lbs, N-mm),
L = Length of Section (in, mm),
h = Length as Indicated (in, mm),
a,b = Distance as shown (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
