In superplastic forming, it is often necessary to control the strain rate. Consider the forming of a hemispherical dome by clamping a sheet over a circular hole and bulging it with gas pressure.
A. Compare the gas pressure needed to form a 2.0-in. dome with that needed to form a 20-in. dome if both are formed from sheets of the same thickness and at the same strain rate.
B. Describe (qualitatively) how the gas pressure should be varied during the form- ing to maintain a constant strain rate.
A gear set has a module of 5mm, a 20° pressure angle, and a 24-tooth case-iron spur pinion driving a 48-tooth case-iron gear. The pinion is to rotate at 50 rev/min. What horsepower input can be used with this gear set if the contact stress is limited..
Steam is leaving a pressure cooker whose operating pressure is 30 psia. It is observed that the amount of liquid in the cooker has decreased by 0.45 gal in 60 minutes after the steady operating conditions are established, and the cross-sectional area..
Evaluate the maximum height reached by the sphere, and the distance traveled by the block.
write a c program calls a function to read a list of n integer values from user input. if user inputs -999 the
a steel ball of diameter 3.0 mm starts sinking with zero initial velocity in olive oil was viscosity is 0.90p. how soon
A power cycle operates between two reservoirs having temperature 700 K and 300K, respectively. QH is the heat (thermal energy) received from the hot reservoir. QL is the heat rejected to the cool reservoir. Wmech represents the mechanical work produc..
Water in the pictured piston cylinder assembly has an initial quality of 10%. The piston cylinder is 20 cm in width and the piston is initially 40 cm high. Heat is added until the temperature of the steam reaches 500°C. While heat is being added the ..
Grains, such as com and sorghum are used to produce ethanol for use in motor oil. A process for producing ethanol from grains is shown in the following figure. What is the control objective of this process
r-134a is contained in a vertical cylinder fitted with a frictionless piston and a set of stops and the volume is
Argon is contained in a 1 L piston-cylinder device at T=300 K and P=100 kPa. Heat is added and the volume is allowed to expand at constant pressure. If the final temperature is 400 K, find the heat added. Assume a constant specific heat capacity. Exp..
Air at 25°C and 1 atm is flowing over a long flat plate with a velocity of 8 m/s. Determine the distance from the leading edge of the plate where the flow becomes turbulent, and the thickness of the boundary layer at that location.
