A cylinderical specimen made of annealed 4135 steel with K equal to 150,000 lb/in^2 and n equal to 0.27 has a diameter of 3 inches and 3 inches high. It is upset at room temperature by open-die forging with flat dies to a height of 2 inches. Assuming the coefficient of friction is 0.2, calculate the final diameter of the specimen after being forged? True strain in the forged specimen? Average pressure at end of stroke? Upsetting force required at the end of the stroke? If friction is neglected, what is the amount of upsetting force?
calculate the pressure drop through the tubes for each selection. Recommend a final design that specidies water-flow rate, tube size, number of tubes, and tube length. Comment on your selection.
If the efficiency of the turbine in converting the mechanical energy given up by the fluid to the turbine shaft is 89% (nt = 0.89), calculate the friction loss in the turbine in J/kg.
Calculate the magnitude of the moment about the base point O of the 600 N force and calculate and draw the shear force and bending moment diagram for the cantilever beam
Determine the minimum coefficient of static friction between the crate and the truck so that the crate does not slide relative to the truck.
What is the advantage of sketching an object first before drawing it using CAD?
A plane can fly 299 mph in still air. If it can fly 180 miles downwind in the same amount of time it can fly 119 miles upwind, find the velocity of the wind.
Draw the block diagram of the uncontrolled seat Plot the open loop displacement response of the uncontrolled seat to a step input
Longitudinal versus Transverse Vibrations in a bar, A 48 inch long by 2 inch diameter round steel rod (E=30e6 psi, density=0.28 lb/in3) is fixed at one end and free at the other. If the rod is struck transversely so that there is both a longitudin..
You are to supply a design for an engine room crane which will provide maintenance support for the main engine. Your design should include the rails the crane will sit on.
(a) Find the rate of heat transfer (kW) to the water. (b) Draw a schematic of the system. (c) Determine the air outlet temperature (°C)
Cantilever Beam with maximum tensile strength. A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I beam to be no..
Acceleration was uniform. If it assumed that the acceleration was uniform where the magnitute of the volocity of an airplane was changed from 120mph to 360mph in 6 seconds.
