Obtain the foundation drawings and soils report for a nearby building. Look first at the log of test borings. What sorts of soils are found beneath the site? How deep is the water table? What type of foundation do you think should be used in this situation (keeping in mind the relative weight of the building)? Now look at the foundation drawings. What type is actually used? Why?
Select the lightest available W14 section for column tosupport the axial compression loads Pd=150k and Pl=200 k if KL =14ft and A572 grade 50 steel is used. Column is assumed to be inframe that is braced against side-sway
determine the elongation of the cable due to its own weight. B. show thet the same elongation would be obtained if the cable were horizontal and if a force equal to half of its weight were applied at each end
A piston-cylinder assembly containing 1/4 kg of a gas undergoes a constant pressure process at 5 bar beginning with a specific volume of 20 m^3/kg. for the gas in the system the work is -15 kj. determine the final volume of the gas in m^3
diameter, are connected by the gears shown. Knowing that G=11.2*10^6 psi, determine (a) the angle through which end A of shaft AB rotates, (b) the angle through which end E of shaft EF rotates.
A 250 cubic meter reaction tank contains a waste water having an ultimate BOD concentration of 755 mg/L. If the BOD reaction rate constant is -0.352/day, how much BOD is remaining after 12.0 days?
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
Design a 2:1 rectangular duct and fan system to pull 40000 scfm of air carrying a medium-density dust through an FCD (Final Control Device) with a ?P of 6.0 in. H2O. Assume the duct system must extend 120-feet and has four 90° elbows.
Explain how to obtain the stress distribution over a section at the base of the chimney, and sketch this distribution over the section.
A Timber power-line pole is 10 in. in diameter at its base where it is solidly embedded in concrete. The pole extends 20 ft vertically upward from its base and is subjected to a horizontal pull of 300 lb at its top.
Determine the stability of the cantilever wall shown in Figure P15.10 and sketch a drainage system to prevent buildup of pore water pressures behind the wall.
Compute the allowable load on a column with fixed ends if it is 5.45 meters long and made from an S150 x 18.6(S6 x 12.5) beam. The material is ASTM A36 steel. Use the AISC formula.
Suppose we want to estimate the average weight of adult males in greater metropolitan Atlanta area. We draw a random sample of 1,000 men from a population of 1,000,000 men and weigh them. We find that the average man in our sample weighs 180 pounds, ..
