- An extruded bar of aluminum alloy has the cross section shown in figure below. A 1.00 m length of this bar is used as a cantilever beam. A concentrated load P = 1.25 kN is applied at the free end and makes an angle of $ = 5p/9 with the x axis. The view in figure is from the free end toward the fixed end of the beam. Determine the maximum tensile and compressive stresses in the beam.
