The wheel on a trolley is held in place on the leg using a 5-mm-radius pin. If the wheel is subjected to a normal force of 10 kN, determine the average shear stress in the pin. Neglect the friction force and assume the pin only supports the vertical 10-kN load

The solid bar has a diameter of 50 mm. The two forces and the torque Tx are acting at the origin of the x-y-z coordinate system which is coincident with the centroid of the cross-section of the bar; the 1800 N force is acting in the y-z plane and torque Tx is acting about the x-axis. Determine the state of stress at points A and B, and show the respective stress components acting on differential elements located at these two points. 200 mm/ y 200 mm 1200 N Tx = 40 N.m %3D 1800 N
