If the load of 4000 lb is lifted by the screw described in Problem 9 at the rate of 0.5 in/s, compute the required rotational speed of the screw and the power required to drive it.
Problem 9
If a square-thread screw having a major diameter of 3/4 in and six threads per inch is used to lift a load of 4000 lb, compute the torque required to rotate the screw. Use a co-efficient of friction of 0.15.
Assuming approximately 19,296 data points can be held in memory, with a 21X Datalogger (CR23X Micrologger), capturing battery voltage; panel temperature; 2 thermocouples
A 110 cm^3 sample of wet soil has a mass of 106 g and a degree saturation of 100%. When oven-dried, the mass is 81 g. Determine the 1) water content, 2) specific gravity, 3) void ratio, and unit dry weight of soil particles.
When are u, v, w maximum, considering are talking about an elliptic shaft
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
Perform laboratory tests on soil samples to determine engineering properties and write the foundation report - collect and analyze the geologic/geotechnical literature for the project area
A tow truck is using a cable to pull a car up a 15 degree hill. If the car weighs 4000 lbs and the cable has a diameter of .75 inches, find the stress in the cable when the truck comes to a stop while on the hill. Ignore friction between the car and ..
A pair of dice is tossed repeatedly. Find the probability that an 11 occurs for the first time on the 6th toss.
The recommended threshhold limit value ( TLV-ACGIH) air concentration for occupational exposure to water-insoluble hexavalent chromium Cr (VI) is 0.01 mg/M^3. this concentration is based on an assumption that the individual is generally healthy and i..
Have each class member write to two or three trade associations at the beginning of the term to request their lists of publications, and then have each send for some of the publications.
A rectangular channel of width 12 ft has an upstream slope of 0.02 ft/ft and a downstream slope of 0.0005 ft/ft. Both reaches have lengths of 500 ft. The upstream reach has a Manning's roughness of 0.016 and the downstream reach has a roughness of 0...
A settling tank in a water treatment plant has an inflow of 2m3/min and a solids concentration of 2100 mg/L. The effluentfrom this settling tank goes to sand filters. Theconcentration of sludge coming out of the bottom (the underflow) is18,000 mg/L, ..
At an angle of α=30°with the vertical, a 5kg sphere is suspended on a string of length .8m with a initial velocity of 1.2m/s, it colides with wedge B. ε=.7 between the .9kg wedge and sphere
