Chapter 3, Problem 3.23P

Line AD is observed in three secwknns, AB, BC, and CD, with lengfl'ls and standard devdlafitinns as listed below. What is the totah length AD and its standard deviatinn?

3. AB = 456.78 :I: 0.03 ft; BC 2 524.50 :1: 0.04 ft}; CD = 692.35 d: 0.05 ft.
b. AB = 299.090 111 :I: 0.005 111;.30 = 336.447 111 :I: 0.006 m;C'D = 465.837 111 :I: 0.008 In

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.
