Determine the lightweight modification factor, λ, for a rectangular beam with b = 16 in. and d = 22 in., four galvanized No. 9 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 4 Grade 60 stirrups located every 12 in. along the span. Assume 5,000-psi normal-weight concrete and a clear cover of 1.75 in.

What was the impact of the Telecommunications Act of 1996 on the radio industry?

A rectangular beam has a cross section of b = 16 in., h = 22 in., and d = 19.5 in. It is reinforced with three No. 6 Grade 60 bars. The concrete strength is 3,700 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. Determine the strength φMn for this beam.
