A computerized design facility has a first cost of $750K. The annual O&M is $100K. The salvage value in year 40 is $5K. Computer monitor replacement will cost $250K every 8 years, and other hardware and software will need replacement every 4 years for $300K. If i = 12%, find the EAC for the 40-year horizon.

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.
