Construct the shear force and bending moment diagrams for the beam shown by the area 
method. Neglect the weight of the beam

Determine the shear and moment as a function of x, and then draw the shear and moment diagrams.

Determine the average shear stress in the 20-mm-diameter pin at A and the 30-mm-diameter pin at B that support the beam shown below. 

A shaft is subjected to a maximum torque of 14 KN-m and a maximum bending moment of 10 KN- m at 
a particular section. Determine the diameter of the shaft according to maximum shear stress theory if the 
elastic limit in simple tension is 180 MPa
