A bar has a cross section in the form of an equilateral triangle, 50 mm on a side. It carries an axial tensile force of 115 kN along with a torque of 775 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.
