Read the project description document thoroughly. 1.Design the three shafts (input, intermediate, and output) needed for your gear box. Shaft material strength must not be higher than AISI 1050 CD Steel. Consider the weight of gears as additional force. Weight of gears can be approximated by assuminggears as cylinders. =42 Here, is specific weight of gear material, is the pitch diameter, and is the face width. All shafts must survive at least 108 cycles with 90% (or more) reliability.Minimum factors of safety are 2 in static and 2 in fatigue failures. Use conservative estimates for fatigue failure.Show all the work and calculations handwritten for all three shafts. You can show results at different points of shaft in tabular format. 2.Determine the critical speed of shafts and make sure the operating speed is less than half of criticalspeed. If not, make necessary adjustments in shaft design. 3.Design four (4) square keys required between the gears and shafts
