Homework Assignment W=1400 N Gear Bearing P=21 kW n =1200 rpm // / L 120 The above figure shows schematically the functional requirements of a power shaft to be designed with the power and transmission requirements. Assuming that the mounting gear is placed to midway between the supporting bearings, please answer the followings accordingly: 1) Determine the dimensions of the shaft. (Determine the diameter and the length of the shaft) 2) Check the design criteria according to the chosen material for the shaft 3) Calculate the critical speed of your designed shaft (in terms of rpm). 4) In order to assemble the gear with the shaft, determine the required key for the design.
