1.For a circular concrete column in a building with a diameter of 12" and subjected to an axial load of 200 kips, determine the stress exerted on the x-section of that column. What type of stress would it be?
2.Assume that gasoline is burned with 99% efficiency in a car engine, with 1% remaining unburned in the exhaust gases as VOCs. If the engine exhausts 16 kg of gases (MW = 30) for each kg of gasoline (MW = 100), calculate the fraction of VOCs in the exhaust. Give answer in ppm.
Water in the amount of 1 lb is contained in a rigid closed tank. Initially the water has a quality of 0.4 at a pressure of 10 lbf/in2. Through a stirrer, work is provided to the water in the tank until the pressure quadruples.
A person of mass 80kg places all their weight on the pedal of a foot operated hydraulic jack. The diameter of the hydraulic cylinder under foot pedal is 4cm and the diameter of the jack cyclinder is 9cm (Assume g is 9.81 m/s^2)
Calculate soil moisture using daily (or any other scale) precipitation and temperature . Use the Richard's Equation and Darcy's law (Or any theory you like attached to soil moisture content determination ).

A powerplant is burning coal on a cold, clear winter morning at 8am with a wind speed of 2.6m/s measure at 30m and an inversion layer with its base height of 697m. The effective stack height is 30m.
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.
A diver is planning to salvage a Spanish galleon located in 200 feet of water. He plans to use a diving suit that will be supplied with air from a hose (assume this to be amply sized) connected to a compressor that he will locate in his boat on the s..
A circular manhole cover has a weight of 250 N and a diameter of 1meter. Surcharged conditions (this means the sewer is flowing full)have developed in the sanitary sewer
For energy conservation, materials with a high thermal capacity are effective in climates in which the heat flow through the building envelope is:
Estimate the number of filters required and calculate the area of each filter (ft2), assuming that a length-to-width ratio (L:W) of 4:1 is employed in constructing the rapid sand filters and suing a filtration rate of 6 gpm/ft2.
