A cantilever beam of T-section is loaded by an inclined force of magnitude 6.5 kN (see figure). The line of action of the force is inclined at an angle of 60° to the horizontal and intersects the top of the beam at the end cross section. The beam is 2.5 m long and the cross section has the dimensions shown.
Determine the principal stresses (1 and (2 and the maximum shear stress Tmax at points A and B in the webs of the beam near the support.
