Determine the lightweight modification factor, λ, for a rectangular beam with b = 16 in. and d = 23 in., five galvanized No. 8 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 8 in. along the span. Assume 6,000-psi normal-weight concrete and a clear cover of 2 in.

The PNP is caring for a child with Pompe Disease. Unfamiliar with the disease, the PNP “googles” the disease and notes it causes tissue damage and destruction from the accumulation excess glycogen not being removed from the cell. The PNP realizes what cellular organelle is involved, as this organelle is responsible for making enzymes and clearing excess substances/waste from the cellular cytoplasm?
