the 30 ft simple beam shown has lateral support spacing at 15 ft for its compression flange and consists of 50 ksi steel. the beam supports a gravity service dead load of 1.2 klf (includes beam weight) and a gravity live load of 3.4 klf. The loads are assumed to act through the e.g. of the section. Select the lightest available W33 section.
aluminum foil used to package food is approximately 0.001 inch thick. assume that all of the unit cells of the aluminum are arranged so that a is perpendicular to the foil surface.
how can Utah and other parts of the country have the same temperature but a different humidity?
The concentration of CO2 is 400ppm what is the equivalent concentration in ug/m^3 at temperature of 22C & pressure of 103.198 kPa.
Compare the size of a CMFR (completly mixed flow reactor) and PFR (plug flow reactor) to achieve 50 percent removal of a contaminant, given a flow rate of 10^4 m^3/d and a first-order rate constant of -0.4/hr. Repeat for 99 percent removal.
A horizontal curve is being designed through mountainous terrain for a four-lane road with lanes 10 ft. wide. The central angle is known to be 40 degrees, the tangent distance is 520 ft., and the stationing of the tangent intersection (PI) is 2600..
A car weighing 4000 pounds strikes the stopping barrier depicted below head on at a speed of 70 mph. The stopping force in the barrier is a function of how far the car penetrates into the barrier.
The area is about 100,000 ha, the ground water pumping about 500 million m3 per year, and the water table drop about 3 m per year. Assuming no replenishment, what is the specific yield of the aquifer material
A 6-inch diameter steel sphere (sg = 8.0) is released in a large tank of oil (sg = 0.86). The terminal velocity of the sphere is measured at 13.5 ft/s. Calculate the absolute viscosity of the oil.
How do you propose to do this at the above treatment plant and estimate the head loss both immediately after backwash and 10 hours later, if the same water is applied at a rate of 2 L/s.m 2 .
A solid steel sphere with a specific gravity of 7.85 and diameter of 0.02 m is falling at its terminal velocity through water at 25 °C. Using either trial-and-error or a graphical approach, determine the velocity of the sphere
The cash flow of alternatives J and K is shown below. If the interest rate is 10% per year, which alternative should be selected. Perform a Present Worth analysis.
An object which has a volume of 0.18 m^3 requires a force of 265 N to keep it immersed in water. If a force of 157 N is required to keep it immersed in another liquid, find the specific gravity of the liquid
