Communication satellites are placed in a geosynchronous orbit,that is, in a circular orbit such that they complete one full revolution about the earth in one sidereal day (23.934 h), and thus appear stationary with respect to the ground. Determine (a) the altitude of these satellites above the surface of the earth, (b) the velocity with which they describe their orbit. Give the answers in both SI and U.S. customary units.
Assume they test null hypothesis H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will the engineers decide to use the steel if H0 is not rejected?
What would happen if the air filter was partially choked. If the piston rings were leaking state what you would expect the results of a, b, c, and d above would be.
the piston has a mass of 4kg and cross-sectional area of 35cm^2. A compressed spring above the piston exerts a force of 60N on the piston. if the atmospheric pressure is 95kPa, determine the pressure inside the cylinder.
Name products that are manufactured using these processes and write two sentences on why you know it's made from this process.
A connection of rod of 50 mm diameter has a rectangular block 50 mm wide and 25mm thick forged at its end. A turned radius of 25 mm joins the rod and the block. Draw the projections of the rod showing curves of intersection.
Please find the mass of gasoline fuel injected into each cylinder in each working cycle.
A Pitot tube measures the total pressure on an airplane flying at sea level as 1.07 x 10^5 N/m^2. What is the velocity of the airplane?
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
Calculate the pressure of 15.0g of methane gas in a 1.50L vessel at 45.0 degrees C using (a) the Ideal Gas Law and (b) the van der Walls equation using the following information about the constants, a and b: a = 2.253 and b = 0.04278.
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..
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
