What type of lubrication should be used for this application?

1.A five-strand no. 40 precision roller chain is being proposed to transmit power from a 21-tooth driving sprocket that rotates at 1200 rpm. The driven sprocket is to rotate at onequarter the speed of the driving sprocket. Do the following:

a. Determine the limiting horsepower that can be transmitted by this drive, and state the governing failure mode.

b. Find the tension in the chain.

c. What chain length should be used if a center distance of approximately 20 inches is desired?

d. Does the 20-inch center distance lie within the recommended range for this application?

e. What type of lubrication should be used for this application?
