1. A simply supported beam has a clear span of 22 ft. and is subjected to a factored uniform load of 3.3 k/ft. The distance from the extreme compression fiber to centroid of longitudinal tension reinforcing steel is 17 inches. Assume f.= 4,000 psi, and fy= 60,000 psi. The factored shear force at the critical section is most nearly: a) 36.3 kips b) 33 kips c) 28.8 kips d) 31.6 kips
