Calculate the compression ratio of an engine with a stroke of 1.5 inches, a bore of 3.8 inches and a clearance volume of 1.25 cubic inches. discuss whether or not this a realistic compression ratio for a street engine and what type of fuel it would need to run correctly. would this engine be considered under-square or over-square?

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.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
