A 3m cantilever beam 260 mm x 485 mm carries a uniformly distributed dead load ( including self-weight) of 14 KN/m along the length and a concentrated live load of 28 KN at the free end. The beam is pre-tensioned with 12mm dia. strands causing a final prestress force of 567 KN. Determine the resulting stress at the top fiber at the fixed end of the center of gravity of the strands is at 112 mm above the NA of the beam, in MPa. Use WSD Method.
