Question: A recatangular beam has a width of 3 0 0 mm and effective depth of 5 7 5 mm . the beam is reinforced for

A recatangular beam has a width of 300mm and effective depth of 575 mm. the beam is reinforced for tension to cause strain in the tension steel to be 0.0018 just as the maximum strain in the concrete reaches to 0.003, use f'c=32 MPa and fy=275 Mpa
1. Determine the depth of compression block?
2.Determine the reduction factor?
3.Determine the nominal strenght of the beam?
