1.Would you expect a crystalline ceramic material to strain harden at room temperature? Why or why not?
2.When making hardness measurements, what will be the effect of making an indentation very close to a preexisting indentation? Why?
3.On the basis of melting temperature, oxidation resistance, yield strength, and degree of brittleness, discuss whether it would be advisable to hot work or to cold work (a) aluminum alloys, and (b) magnesium alloys
4.Briefly explain why a proeutectoid phase (ferrite or cementite) forms along austenite grain boundaries.
A two-bed carbon adsorption system is to be designed to handle 8000 acfm of air containing 700 ppm of hexane. Laboratory studies indicate that carbon can adsorb 8lb hexane per 100 lb carbon under the conditions at which the system will be operated.
determine the power developed by the force when t = 5s. Hint: First determine the time needed for the force to cause motion.
A block of material has a mass density of 650 kg/m^3 and volume of 0.37 m^3. Find the weight of the block in Newtons and the specific gravity of the material. What downward force (in Newtons) would be necessary to hold the block from the previous pro..
A fully loaded, ocean going container ship is just stable about its longitudinal axis (roll). The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the ..
The student strikes the sign at a speed of 25 mi/h. if the student was travelling at 65 mi/h when the sign was first spotted, what was the student's associated perception reaction time
An asset has an initial cost of $45,000 at the end of 4 years the salvage value of the asset is $5,000. Using the sum of the years' digits, calculate the accumulated depreciation at the end of the 4 years.
A car starts from rest and moves along straight line with anacceleration of a = (3s-1/3)m/s2, where s is in meters. Determine the car'svelocity and position when t = 6s
A chemical plant uses a tube-within-a-tube counterflow heat exchanger to heat air with the use of steam. During steady state operation, the air flows into the exchanger at a rate of 5,000 kg/h and a temperature of 27C and exits at a temperature..
Formulate a Linear Program for Blend Mix at Bluegrass Distillery, The Bluegrass Distillery produces custom-blended whiskey
The soil undergoes shear failure and reaches critical state on this plane when the pore-water pressure is increased to 120 kPa while keeping the total normal and shear stresses constant.
A cylinder fitted with a piston has a volume of 2ft^3 and contains 0.5 lbm of steam at 60 psia. Heat is tranferred to the stream until the temperatureis 500 F, while the pressure remains constant
