A simply supported beam with dimensions of b = 18 in., h = 24 in., d = 21.5 in., and L = 19 ft supports a uniform service (unfactored) dead load of 2.05 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 10,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 108 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 128.6 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.1961 in.

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 18 ft supports a uniform service (unfactored) dead load of 1.466667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 3 No. 8 bars. The concrete strength is 8,200 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.

The FNP is concerned that her female patient admits to drinking a bottle of wine most evenings. The FNP counsels her patient that more than 1 drink per day increases the risk for many disease states including cancer. The FNP realizes this is because the body metabolizes alcohol into which substance which is toxic to most tissues?
