A 4 in. in diameter shaft moves through a well-oiled sleeve that is 12 in. long. The force required to move the shaft is 25 lbf, and the shaft velocity is 5 in./s. The oil-filled clearance between the shaft and the sleeve is 0.005 in. Calculate the viscosity of the lubricating oil (a Newtonian fluid).
Of this total, 2000 acres are residential(CN=68), 500 acres are industrial (CN=88), and 2500 acres are forest with good cover (CN=55). For a design storm of with a total precipitation of 7 inches, estimate the direct runoff in inches.
A Class I rural highway segment of 10 miles in level terrain has a base free-flow speed (BFFS) of 65 mph. The cross section has 12-ft lanes and 6-ft clear shoulders on both sides of the road.
A gray silty clay (CL) is sampled from a depth of 12.5 feet. The "moist" soil was extruded ffrom a 6-inch high brass liner with an inside diameter of 2.83 inches and weighed 777 grams.
Create a MATLAB program and flowchart which will allow the user to input an unknown number of temperatures, each of which might be a temperature in Celsius, Fahrenheit, Kelvin, or Rankine, and will convert the user input temperature to each of the..
If a watershed of drainage area 100 mi^2 has abstractions of 2.5 in/hr, what runoff volume will show up in the nearby stream in addition to baseflow for a rainfall of 5-hr duration with an intensity of 4 in/hr
The total number of effective exposures per unit of advertising medium depends on the region reached. In Louisiana, the number of effective exposures is 70,000, 100,000 and 75,000 for television, radio and direct mail, respectively.
An airport corridor is 30 ft wide. given a peak demand of 300 pedestrians per minute and an average walk speed of 3 ft/s, estimate the LOS at the corridor
A soil sample is obtained by pushing a 16 inch long tube into the side of a pit. The tube has an inside diameter of 3 inch and weighs 1.8 lb. The soil in the tube is trimmed so that its ends are flush with the ends of the tube.
A 600 mm long solid steel shaft is to transmit a torque of 30 N-m, G=90 GPa, diameter 15mm. Determine (a) Maximum shear stress, and (b) Angle of twist (phi) at the end.
two strips of a plastics material are bonded together as shown. The average shearing stress in the glue must be limited to 1000 kpa. what length L of splice plate is needed if the axial load carried by the joint is 55 kN and the width (W) is 315 m..
Air photos are taken with specified overlap to take advantage of image parallax. Calculate the time interval between air photo exposures if the ground speed of the aircraft is 160km/h, the focal lenght is 50mm
A torque of T = 3.00 kN-m will be applied to the hollow thin-walled aluminum alloy section. If the section has a uniform thickness of 4 mm, determine the magnitude of the maximum shear stress developed in the section.
