An embarkment will be constructed with the soil compacted to 95 percent of the max dry density. the borrow material, is deposited at a uniform density of 75 percent of the max dry density. the roadway embankment will require 75,000 cubic yards of fill. how many yards of borrow will be required to complete construction of the embankment?
For energy conservation, materials with a high thermal capacity are effective in climates in which the heat flow through the building envelope is:
The compound bar carries the axial forces P and 2P. Find the maximum allowable value of P if the working stresses are 40 ksi for steel and 20 ksi for aluminum, and the total elongation of the bar is not to exceed 0.2 in.
a two story school has interior columns that are spaced 15 ft apartin two perpendicular directions. If the loading on the flat roof isestimated to be 20 lb/ft^2 determine the reduced live loadsupported by a typical interior column at (a) the ground f..
Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough.
The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in
Biological treatment processes for wastewater can be categorised as dispersed growth and attached growth systems. Discuss the advantages and disadvantages of attached growth systems over dispersed growth systems.
The beam is loaded with a concentrated live load of 10 kips at the center of its span, in addition to its own weight.. The dead load includes the beam weight. The steel is A242, Grade 50.
Simply Supported Reinforced Concrete Beams - Explain the purpose and amount of reinforcing in concrete beams in relation to bending and shear and the concepts of under reinforcement, balanced reinforcement and over reinforcement.
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
Measure the distance PA, PB, PC etc. from p to various point with chain or tape and plot them to scale along the co responding rays. Join the points a, b, c, etc. to give outline of survey.
A 2000-lb wheel load is to be supported by aggregate over soil with a maximum bearing pressure of 1000 lb/sqft. What depth of aggregate is needed if the angle theta is 40 degrees?
The bar AB has an axial rigidity of EA. The bar is rigidly attached at A while there is a gap at B. A load P acts at point C and has a large enough magnitude to close the gap at B.
