Problem 7.29 Given: An extruded bar of aluminum has the cross section shown. A 2.10-m length of this bar is used as a simple beam on a span of 2.0 m . A concentrated load of P = 5.0 kN is applied at midlength of the span and makes an angle of φ = 1.4 rad with the x axis. Find: The maximum tensile and compressive stresses.
