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.

Calculation Example – Internal forces.

Determine the internal forces at point C.

Determine the magnitudes of F1,F2 and the angle Θ so that the external forces and the external moment create a zero resultant force and moment at the wheel (Radius=3m, units KN,m, degrees).

Determine the shear force and moment acting at a section passing through point C on the beam.
