An electrical contact material is produced by infiltrating copper into a porous tungsten carbide (WC) compact. The density of the final composite is 12.3 g/cm3. Assuming that all of the pores are filled with copper, calculate
(a) the volume fraction of copper in the composite,
(b) the volume fraction of pores in the WC compact prior to infiltration, and
(c) the original density of the WC compact before infiltration.
At the inlet to an axial diffuser the velocity of the approaching air is 420 m/s, the stagnation pressure is 300 kPa, and the stagnation temperature is 600 K.
a gasoline delivery truck traveling at 80 kmhr decelerates at a constant rate to a complete stop 10 seconds. the
A train car has a mass of 17500 kg and is travelling at 10 m/s to the right on a horizontal track. At the same time, another train car with a mass of 12500 kg is travelling on the same track at 6 m/s in the opposite direction. The coefficient of kine..
The purpose of this project is to introduce you to the application of FEA by using the ANSYS software to examine the deflection of an I-beam under a point load.
Use the USDA Quick Stats service (http://quickstats.nass.usda.gov//) to compare the 2009 oat yields between New York and California. What additional land would California require to meet the same amount of oat production as New York?
An inventor claims to have developed a power cycle operating between hot and cold reservoirs at 1175K and 295K, respectively, that provides a steady state power output of (a) 28 kw, (b) 31.2 kW, while receiving energy by heat transfer from the hot re..
In the short-circuit test, we assume that V˜ secondary is zero, so that the voltage on the primary side of the ideal transformer is also zero, causing no current flow through the rc - Lc parallel combination. Using this assumption with the short-c..
