Air that has a total mass of 0.1 lbm is confined inside a piston-cylinder system with a temperature of s5 °f and a pressure of 30 psi heat is added to the system while maintaining a constant pressure and as a result, during the process, the 6 in diameter piston rises a distance of 11.3 in. calculate (a) the work done per unit mass in [ft-lb/lbm] and (b) the change in specific internal energy in [btu/lbm] for this process.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
