Which structure is unique to males only?

A simply supported beam with dimensions of b = 14 in., h = 26 in., d = 23.5 in., and L = 22 ft supports a uniform service (unfactored) dead load of 1.479167 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.9 kips/ft. The beam is reinforced with two No. 6 Grade 60 bars. The concrete strength is 7,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Using the effective moment of inertia, determine the immediate mid-span deflection of the beam due to the combined service loads (dead plus live).The effective moment of inertia Ie = 5,939.7 in.4.

Determine the epoxy modification factor, ψe, for a rectangular beam with b = 16 in. and d = 22 in., five epoxy-coated No. 9 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 4 Grade 40 stirrups located every 6 in. along the span. Assume 7,000-psi normal-weight concrete and a clear cover of 2 in.
