In the previous problem, if the remote loading includes both mode I and mode II, i.e. KI and KII, derive expressions relating k1 and k2 to KI and KII in terms of the tilt angle, a.
assume lateral support at each support and every 20 ft between supports. assume constant depth for girder. use A 572 grade 50steel. use LRFD methods. minimum web thickness is 5/16 inches.
Part of a vertical piping system consists of 8 ft of 4 in diameter, connected to 8 ft of 3 in diameter above, and connected to 8 ft of 2 in diameter above that. Water at 60 F flows up the pipe (no downward flow occurs)
A bucket full of water is to be rotated in the vertical plane. What minimum angular velocity, in rad/s, is necessary to keep the water inside if the rotating arm is 120 cm
Explain why the maximum flow rate per unit area for a given gas depends only on P0/ 0.For an ideal gas with k = 1.4 and R = 0.287 kJ/kg · K, find the constant a such that m . /A* = aP0/0.
For arectangular section (b(width) x h(thickness) that is subjected to aforce P that is applied at an eccentricity (e) measured from thecenter of area of the rectangle in the h (thickness) direction.
The new owners propose to flush the pond into their discharge pipe leading to the Atlantic Ocean, which has a salt concentration above 30,000 mg/L. What flow rate of fresh water (in m3/s) must they use to reduce the salt concentration
A static thrust stand is to be designed for testing a specific jet engine. Knowing the following conditions for a typical test,
The vehicle has a frontal cross -sectional area of 1.9 m^2. The roadway has a straight alignment and a badly patched and broken asphalt surface. assume a drag coefficient of 0.3 and p of air of 1.29 kg/m^3
A hemispherical bowl of radius r connected to a U-tube of constant radius r. Initially the the bowl is empty and the air/manometer liquid interface in both legs is at the level of the bottom of the bowl
Traffic signals were installed at an intersection involving two one-way streets. Suppose 75% of the vehicles will decelerate when they see the amber light, whereas 20% will accelerate and 5% are "indecisive" and simply continue with the same speed..
A power plant emits 95 g/s of SO2 from an effective stack height of 60 m. The wind speed is 3 m/s and the solar insolation is slight.
Statistics indicate that the world population since World War II has been growing at the rate of 1.9% per year. Further, United Nations records indicate that the world population in 1975 was (approximately) 4 billion.
