A) What is the maximum load that a .75" diameter steel cable can hold if the UTS of the steel is 145,000 PSI and a safety factor of 1.5 is required?
B) What is the stretch of the 360" cable under this load? Assume E = 30E6 PSI
One way to treat amd is to treat the metals in a holding pond. The first order rate constant is 10/day. The concentration in the water must be below 5 ppm. How long in hours will it take to reduce the concentration from 250 ppm to 5 ppm
A rectangle commercial building must be laid out 200.00 ft wide and 300.00 ft long. if the steel tape used is 100.02 ft long under standard conditions, what distances would be laid out?.
1. A block of moist soil weighs 12.72 lbs, is 0.1050 ft3 in volume, has a water content of 9.5%, and has a specific gravity of soil solids of 2.7. Assess: Va, Vw, Vs, S, e, gama d. 2. The moist unit weight of a soil is 18.7 kN/m3 Given that Gs=2.71..
Using the data available in Appendix B, determine the slope of the line when the plate is subjected to a 45-kip centric axial load.
An engineering student is driving on a level roadway and sees a construction sign 500 ft ahead in the middle of the roadway. the student strikes the sign at a speed of 25 mi/h.
Each week a hen can either lay 12 eggs or hatch 4 eggs, but not both. At the end of the four-week period all eggs and chicks will be sold: an egg will bring 10 cents, and a chick will bring 60 cents.
Do you believe it is plausible that the blocks do not meet the specification, or are you convinced that the blocks meet specification? Explain your reasoning.
A completely reversible heat engine operates with a source at 1500 R and a sink at 500 R. At what rate must heat be supplied to this engine, in Btu/h, for it to produce 5 hp of power
A power plant operates at steady-state. It receives energy from a hot source (combustion of fuel) at a temperature of 420 oC. The plant discharges this energy to a nearby river that acts as a cold source.
A sanitary landfill project needs an import soil for use as an impervious cap over the refuse. The design engineer desires a soil with a high clay content because it will help keep water out of the landfill.
If the discharge is 500cfs, what power output may be expected from the turbine? Assume that the turbine efficiency is 90% and that the overall head loss is 1.5V 2/2g, where V is the velocity in the 7 ft penstock. Assume a=1.0 at all locations.
The porosity of both media is 0.40, the shape factor for the anthracite is 7.5, and the shape factor for the sand is 6.0. Assume a water temperature of 60 F.
