Problem #1. The base of a rectangular reinforced concrete beam is 300mm and the effective depth is 550mm. Concrete compressive strength on the 28" day is 24MPA and steel yield strength is 415MP.. Determine : a. The depth of compression block (in mm, 2 decimal places), the strain in the tension steel (5 decimal places) and ultimate moment capacity (in KN.m, nearest tenth) of the beam if it is reinforced with 4-32mm diameter bars. b. The depth of compression block, the strain in the tension steel and ultimate moment capacity of the beam if it is reinforced with 4-20mm diameter bars.

Please solve with complete detailed solution. Thank you.
just answer d to f
A 300mm x 425 rectangular beam is reinforced for tension only with 4-28mm bars. The beam has a concrete cover of 40mm and a stirrup of 10mm diameter bar. The beam carries a live load and a dead load (without its self-weight). Given that unit weight of concrete is 24kN/ cu.m f'c = 21 MPa and fy = 414 MPa, calculate the additional concentrated live load as shown in the figure.
