A storage tank holds 75 cubic meters of a gas at 28deg C and a pressure of 130kPa. The gas appears to have a molecular weight of 30 from tests run in a laboratory. Estimate the mass of the gas in the tank in kg assuming the gas behaves as an ideal gas. If the gas warms up to 35 deg C as it sits in the sun all day, what would the pressure rise to?
Determine the tensions developed in wires , and and the angle required for equilibrium of the 30-lb cylinder E and the 60-lb cylinder F.
Determine if the shaft has infinite fatigue life. If not, determine the number of cycles to failure. Also determine the safety factor for first cycle yield and draw a free body diagram, shear and moment diagrams, and graph the loads on the shaft..
A wooden board AB, which is used as a temporary prop to support a small roof, exerts at point A of the roof a 57-lb force directed along BA. Determine the moment about C of that force.
Estimate the blood pressure in each branch, assuming that blood vessels behave as rigid tubes, that we have frictionless flow, and that the vessel lies in the horizontal plane. What is the force generated at the branch by the blood? You may approx..
