Problem 1: 12" A rectangular reinforced concrete beam with dimensions b 14 in, d 25 in, and h 28 in is reinforced with three No 10 bars. Material strengths are f, 60,000 psi 24 and f' 5000 psi. 21 %3D (a) Find the moment that will produce the first cracking at the bottom surface of the beam, basing your calculation on Ig, the moment of inertia of the gross concrete section. (b) Repeat the calculation, using It, the moment of inertia of the uncracked transformed section. (c) Determine the maximum moment that can be carried without stressing the concrete beyond 0.45 f. or the steel beyond 0.60 fy.
