1. You would like to produce a gray iron casting that freezes with no primary austenite or graphite. If the carbon content in the iron is 3.5%, what percentage of silicon must you add?
2. We would like to produce a 2-in.-thick steel wear plate for a rock-crushing unit. To avoid frequent replacement of the wear plate, the hardness should exceed HRC 38 within 0.25 in. of the steel surface. However, the center of the plate should have a hardness of no more than HRC 32 to assure some toughness. We have only a water quench available to us. Design the plate, assuming that we only have the steels given in Figure 13-21 available to us.

A cube of wood having an edge dimension of 20.0 cm and a density of 650 kg/m3 floats on water.
What is the composition of the alloy and what is the temperature at which the first solid phase solidifies? (Estimates rounding to convenient numbers are sufficient.)
An 8-kg plunger is released from rest in the position shown and is stopped by two nested springs; the constant of the outer spring is k1 = 4 kN/m and the constant of the inner spring is k2 = 12 kN/m. If the plunger is released from the height

A high-speed boat is powered by a water jet pump engine, similar to a jet engine on airplanes. The engine takes in water at the bow through a tube with diameter 1 ft, and the water is pumped out the stern of the boat through a 3-in diameter tube.
a rectangular tank open to the atmosphere is filled with water to a depth of 2.5 m as shown. a u-tube manometer is
a 45-g bullet is fired with a velocity of 600 ms into a wooden block which rests against a solid vertical wall. knowing
A part of a duct system is a 10-by-22-in rectangular main duct carrying 1600 cfm of air. A tee to a branch duct, 10 X 10 in, draws 500 cfm from the main. The main duct remains the same size downstream from the branch. Determine the velocity of flo..
Describe a physically-plausible situation where the Reynolds number is (a) 1 (b) 10,000 (c) 1,000,000. For flow in tubes/pipes/ducts, use Red For flow over/along long/blunt objects, use Rel.
an advertising sign is suspended from a horizontal rod and is allowed to swing under wind forces. the rod is to be
Determine the heat transfer rate from the steel plates of Problem 7.24 accounting for free convection from the plate surfaces. What is the corresponding rate of change of the plate temperature?
1. A cylinder of 120-mm diameter at 1000 K is quenched in saturated water at 1 atm. Describe the quenching process and estimate the maximum heat removal rate per unit length during the process.
