A simply supported reinforced concrete beam is loaded under uniformly distributed load. The span of the beam is 10'. f = 4000psi and fy = 60000psi, Assume n=9 a. Assuming the concrete is uncracked, compute the stresses in concrete and steel in the following beam for a bending moment of 25 ft-k. b. Determine the cracking moment of the section c. Compute the value of load (W) at which cracks will appear at the bottom of the beam W(k//ft)=? h = 18 in. b = 12 in. 3#9 bars 10' d = 15 in.
