Acylindrical powder compact with an outer diameter do and inner diameter di is to be pressed by means of single-action compaction. derive an equation analogous to eq. 7.71 that would be appropriate for this geometry. hint: for this geometry, the normal force on the compact, fn, may be represented in terms of the applied pressure as follows: f= z x p x pi ( do + di ) dh

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
