Vehicles arrive at a tollbooth according to the function h(t)= 5.2-0.2t, where h(t)is in vehicles per minute and t is in minutes. The toll booth operator processes 3 vehicles per minute. Determine the total delay, maximum queue length, and the time it takes the 20th vehicle to arrive waits from its arrival to it departure
A particle moves along the positive x-axis with an acceleration in meters per second squared which increases linearly with x expressed in millimeters, as shown on the graph for an interval of its motion.
Consider the two loading scenarios on the beam, where the beam is supported by a pin joint on the left and roller joint at the right end. What are the internal forces and moment at point A for each scenario
H = h - N. At point A, the geoid correction is -100 feet; the ellipse height is 100'. What is the NAVD88 elevation of point A
consider the cantilever beam-mass system. formulate and solve the minimum weight design.
Provide the minimum number of ports. The design conditions are: Winter design fl ow rate 4,300 m 3 /d Minimum river elevation held constant by lock and dam system 99.0 m 500-year fl ood elevation 113.3 m River bottom elevation 90.4 m
Determine the flow rate of water (20 degrees celcius) that will cause a pressure drop of 17250 N/m^2 in 350m of horizontal, cast-iron pipe (d=60cm). assume minor losses are negligibe
A CMFR is to be designed to remove contaminant A from water with a steady-state efficiency of 95 percent. The decay reaction is zeroth order, with a rate constant of 0.1M/h. The inlet concentration of A is 0.5 M.
How does the engineering classification of soils differ from he engineering classification of rocks
If the time required to pay for parking is exponentially distributed with a mean of 15 seconds, find the average time in system.
Two toll booths are open and each can process arrivals (collect tolls) at a mean rate of 12 seconds per vehicle ( the processing time is also exponentially distributed). What is the total time spent in the system by all vehicles in a 1 hour period
A freeway exit ramp has a single 12-foot lane and consists entirely of a curve with a central angle of 90 degrees and L=628 feet. If the distance cleared of obstacles is 19.4 feet from the centerline, what design speed was used
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
