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)

Calculation Example – Torsional moment-Stress. Featured

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.

Calculate tension force F_AC in cable AC using virtual work for the weight of 10 KN. (The equilibrium is at φ=45 degrees)

A copper bar with a rectangular cross section is held without stress between rigid supports. The temperature of the bar is raised 50°C. Determine the maximum shear stress t. (Assume α= 17.5 x 10-6/°C and E =120 GPa.)

Determine the moments of inertia Ix and Iy of the Z section. The origin of coordinates is at the centroid.
