meet the lips, to 2.54 mm at their junctions with the web. The web has a constant thickness of 2.54 mm and the shear modulus G is 26 700 N/mm². Calculate the maximum shear stress in the section and also its rate of twist if it is subjected to a torque of 100 Nm. Ans. Tmax = ±297.4 N/mm², d0/dx= 0.0044 rad/mm.
