In designing a fixed-incline self-acting thrust pad when the width of the pad is much larger than the length, it is of interest to know the magnitude and location of the maximum pressure. The viscosity of the lubricant is 0.05 N-s/m2, the sliding velocity is 10 m/s, the pad length is 0.3 m, the minimum film thickness is 15 m, and the inlet film thickness is twice the outlet film thickness.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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.

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)
