The gear ratio shown must transmit 10 horsepower (66000 lb in/s) from its input, which is rotating at a speed of 1200 revolutions per minute. It must increase the torque received at its input shaft 16 times. Spur gears with 20° pressure angle should be used. Input and output shafts should be aligned. The transmission should take up as little space as possible. The distance between the centers of the input shaft and the intermediate shaft (the one that loads gears 3 and 4) should be 10 inches. Determine the magnitude of the radial load that gear 4 exerts on gear 4. Write your answer in pounds.
A gearbox is needed to provide an exact increase in speed, while minimizing the overall gearbox size. The input and output shafts should be in-line. Specify appropriate teeth numbers. The gearbox is required to transmit 18 kW from a shaft rotating at 2650 rpm. The desired output speed is exactly 13250 rpm.
