Chapter 2, Problem 18QAP

Vehicles begin to arrive at an amusement park entrance at 8:00 A.M. at a rate of 1000veh/h. 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)?

1. For truss given in a figure below, determine reactions, and forces in all truss members. De- termine forces using two methods independently: (a) method of joints, and (b) method of sections. Compare your results and verify that your solutions are accurate. Assume that force F = 10kN. 2m 2m 2m ▼F ▼F 4m ▼F 4m

1) Determine if the existing sedimentation basins are sufficient to accommodate the projected future capacity. If not, design upgrades to the sedimentation basins. A) Current Capacity: 22.5 MGD B) Future Capacity: 34.5 MGD for 110,000 residents C) If not, design upgrades to the sedimentation basins. 2) Specify the design flow rate, the type of basin (circular vs. rectangular) 3) Specify the basin dimensions (length, width, water depth or diameter and water depth). 4) Specify the dimensions of the launders (if applicable) and the length of the weir.

= The frame shown is fitted with three 50 cm diameter frictionless pulleys. A force of F = 630 N is applied to the rope at an angle ◊ 43°. Member ABCD is attached to the wall by a fixed support at A. Find the forces indicated below. Note: The rope is tangent to the pully (D) and not secured at the 3 o'clock position. a b •C *су G E e d BY NC SA 2013 Michael Swanbom Values for dimensions on the figure are given in the following table.

The lower jaw AB [Purple 1] and the upper jaw-handle AD [Yellow 2] exert vertical clamping forces on the object at R. The hand squeezes the upper jaw-handle AD [2] and the lower handle BC [Orane 4] with forces F. (Member CD [Red 3] acts as if it is pinned at D, but, in a real vise-grips, its position is actually adjustable.) The clamping force, R, depends on the geometry and on the squeezing force F applied to the handles. Determine the proportionality between the clamping force, R, and the squeezing force F for the dimensions given. d3 d4 R 1 B d1 2 d2 D... d5 F 4 F Values for dimensions on the figure are given in the following table.
