A simply supported beam for a building interior with 18 ft span has a cross
section of 12 in width and 21 in overall depth. The beam is made with 5 ksi
compressive strength concrete and 60 ksi reinforcing steel. The beam supports a
uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live
load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart
c/c. Design this beam and show in a sketch.

Some of these vehicles have electronic identifiers that allow them to enter the park immediately, beginning at 8:00 A.M., without stopping (they are billed remotely). All vehicles without such identifiers stop at a single processing booth, but they wait in line until it opens at 8:10 A.M. Once open, the operator processes vehicles at μ(t) = 8 + 0.5t [where μ(t) is in vehicles per minute and t is in minutes after 8:10 A.M.]. An observer notes that at 8:25 there are exactly 20 vehicles in the queue. What percent of arriving vehicles have electronic identifiers and what is the total delay (from the 8:00 A.M. until the queue clears) for those vehicles without the electronic identifiers (assume D/D/1 queuing)?arrow_forward
