A2-in. diameter horizontal shaft is supported by two sleeves, each of length = 2 in. the internal diameter of the sleeves is 2.1 in. the radial space between the shaft and the sleeves is filled with an oil of viscosity = 8x10 needed to move the shaft at a velocity of 1 fus. lb-s/ft'. what is the force

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.
