sel engine for a commercial boat operates at 200 rpm and delivers 800 hp through a 1) A die with a ratio of 4 to 1 to the propeller as shown below. Because the propeller shaft gearbox ed is four times that of the crank shaft, the torque on the propeller shaft is one-fourth that spe o the crank shaft. Both the shaft from the engine to the gearbox and the propeller shaft are to be solid and made of...

1. A motor delivers 120 hp at 250 rpm to a radial pump through a flanged coupling mounted on a 0.375-inch diameter steel shaft. The pump is mounted on a 0.3125-inch diameter steel shaft and the two shafts are connected by flanged couplings. The flanges are connected using 2.000-inch long, 0.25-inch diameter, SAE Grade 4 steel bolts, equally spaced along a 3.5-inch diameter bolt circle. The coupling flanges are 4 inches in diameter and 0.75 inch thick. The bolts are...
