Based on the knowledge that it takes about five hours to change out the main drive belt, would you consider the replacement interval estimate in (a) to be acceptable?
1. A D-section V-belt is to be used to drive the main power shaft of an agricultural combine (an agricultural combine may be regarded as a combination of conveyors, elevators, beaters, and blowers). The power source is a 6-cylinder, 30-hp internal combustion engine which delivers full-rated power to a 12-inch-diameter drive sheave at 1800 rpm.…

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…

estimate the “additional stretch” that would occur in the rope if a 750-lb load were being lowered at the rate of 2 ft/sec, and when the load reaches a point 10 feet below the 7.0-inch drum, a brake is suddenly applied.
1.It is desired to market a small air-driven hoist in which the load is supported on a single line of wire rope and the rated design load is ton (750 lb). The wire rope is to be wrapped on a drum of 7.0 inches diameter. The hoist should be able to lift and lower the…

estimate the number of lifts that could be safely made under the mixed loading described in (b). Again, use a fatigue safety factor of 1.25 in your estimating procedure.
1. An electric hoist, in which the load is supported on two lines, is fitted with a -inch improved plow steel (IPS) wire rope that wraps on an 8-inch-diameter drum and carries an 8-inch sheave with an attached hook for load lifting. The hoist is rated at 1500-lb capacity. a. If full-rated load were lifted…

calculate whether the 1.38-inch-diameter journal is properly designed to safely withstand the fatigue loading.
1.The cylindrical bearing journal of a straddle-mounted crankshaft has been tentatively sized based on wear requirements, and it has been found that a diameter of 1.38 inches is required for this purpose. A force analysis of the journal at the critical cross section has shown there to be a transverse shear force of 8500 lb,…

Design a suitable crankshaft and construct good engineering sketches of the final design.
1.A straddle-mounted crankshaft for a belt-driven singlecylinder refrigeration compressor is to be designed to meet the following specifications: a. The force on the connecting rod bearing ranges from 3500 lb down to 1300 lb up. b. The belt tension ratio is . c. The crank throw is 2.2 inches. d. Allowable maximum bearing pressure is…
