A room has 10 cotton spinning looms. Once the looms are set up, they run automatically. The setup time is exponentially distributed, with mean 10 minutes. The machines run for an average of 40 minutes, also exponentially distributed. Loom operators are paid $10 an hour, and looms not running incur a cost of $40 an hour. How many loom operators should be employed to minimize the total cost of the loom room? If the objective becomes "on the average, no loom should wait more than 1 minute for an operator" how many people should be employed? How many operators should be employed to ensure that, on average, at least 7.5 looms are running at all times?
ABC is a triangular tract of land. The 1.5 tract DEFG is to be subdivided. AE is 480ft and DC is 350 ft. Determine the lengths of DG and CB. (Note 1 acre= 43,560 f^2)
An industrial building has floor area of 5 m by 8 m and is 3 m high with a door 1 m wide and 2 m high. Leakage of transformer oil from a pump occurs and is ignited. What is the maximum area of spill in (m^2) if flashover is to be avoided.
A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12 feet, and the superelevation is 0.06 and was set assuming maximum fx.
A dry quartz sand has a unit weight of 100 pcf. What is the soil's unit weight when the degree of saturation is 75% if Gs = 2.66
The beam is simply supported and spans 25 feet. The beam must be designed for a superimposed uniformly distributed dead load of 1 kip/ft, and a concentrated live load of 12 kips that acts 10 feet from one of the supports.
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
