Noncircular Sections-Combined Normal and Torsional Shear Stresses A square bar is 25 mm on a side and carries an axial tensile load of 75 kN along with a torque of 245 N-m. Compute the maximum shear stress in the bar. (Note: Refer to Section and Figure .) a crank to which a force F of 1200 N is applied. Compute the maximum stress in the circular portion of the crank.
