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?
A flywheel can be considered as being composed of a thin disc and a rim. The rim weighs 322 lb and has diameters of 24 in. and 30 in. The disc weighs 64.4 lb. Determine the mass moment of inertia about the centroidal axis about which the flywheel ..
A thin electric heater is wrapped around a rod of diameter 3 cm. The heater dissipates energy uniformly at a rate of 1300 W/m. Air at 20°C flows normal to the rod with a velocity of 15.6 m/s. Determine the steady state surface temperature of the h..
Weld analysis, Two steel plates are joined with a butt weld using a weld throat h of 3/8 in. and the length of weld 1 of 4in.

A plate, 0.001 in distant from a fixed plate, moves at 2 feet per seconds and requires a force of 0.04l bar per feet square to maintain this speed. determine the fluid viscosity of the substance between the plate.
What is the compressor's steady state response when a 30kg absorber with a stiffness of 1.3*10^5 N/m is added to the end of the beam? Please determine how to change the absorber to minimize the response of the beam.
a disk has a mass of 4kg and a radius of 90mm, it is at rest when it is placed in contact with the belt, which moves with a constat speed (v =15m/s). knowing that friction is .25 between the disk and the belt. Determine the number of revolution by..
