Solution

Shear diagram

 Moment diagram

Determine the equation of the elastic curve for the beam using the x coordinate. Specify maximum deflection. EI is constant.

Calculate the internal normal forces at points A,B,C for the rod which is loaded with the forces shown.

Draw the shear and moment diagrams for the cantilever beam (units KN,m).

Calculate the internal forces for the cantilever beam with the uniform loading q=10KN/m.

A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)

Calculate the max stress because of torsional moment on the outer layer of a steel hollow rod when two forces act on it from a distance of 100mm from the center.
