A rectangular cantilever beam has a width of 300mm and an effective depth of 480mm. It is reinforced with 7-25mm bars. The beam is carrying a uniformly distributed dead load of 15kN/m. The compressive strength of the concrete is 21MPa and the yield strength of the steel is 415MPa. The nominal moment capacity multiplied by its strength reduction factor is 334kN.m. Determine the allowable concentrated live load in kN that it could carry acting at 2.89m from the support if the length of the beam is 2.24m. Note that the dead load includes the weight of the beam.
