Acylinder, closed by a piston, has a volume of 0.03m and contains air at 1 bar and 15°c. the air is compressed isentropically to one quarter of its original volume. it is then cooled in a reversible constant pressure process until the temperature falls to its initial value. finally, the air is expanded isentropically back to 1 bar. find the final temperature and the net work done during the sequence of processes.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero
