ARTURO: Este domingo tengo que limpiar la casa. ANA: ¡Oh no! Mis compañeras y yo [q21] limpiamos ayer. ARTURO: Nosotros ayer tuvimos una cena con amigos y hoy tengo que lavar los platos. ANA: ¿[q22] vas a lavar ahora? ARTURO: Sí, y después tengo que limpiar mi dormitorio. ¿Tú también [q23] limpiaste ayer? ANA: No. Por la noche mis amigas y yo miramos dos películas en Netflix. ¡[q24] recomiendo porque son muy divertidas!

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.
