A rectangular reinforced concrete beam with width of 350 mm and effective depth of 600 mm is subjected to 250 Kn.m bending moment. the beam is reinforced with 6-25 mm bars. Use alternate design method and modular ratio, n = 10.
a. find the location of the neutral axis from the bottom of the beam & moment of Inertia.
b. Find the maximum stress of concrete and steel
c. total compression force in concrete?
