A cone clutch with a cone angle (a) 12.5 transmits and control 20 kW power at 500 rev/min from an electric motor to gearbox. A clutch pedal lever mechanism attached to the shifting groove is used by an operator to engange or disengage the cone clutch. The coefficient of friction is 0.25 and the allowable pressure for friction material is 400 kPa. The ratio of the lever mechanism (a/b) is 0.5. The clutch outer diameter must be fixed as 40 cm due to design space limitations. Assuming the clutch will be worn based on uniform wear theory, determine a) the inner diameter, b) the face width of the friction lining (friction area), c) the operator pedal force required to disengage the clutch. d) If an average operator can push the pedal with a 350 N force in a sitting position, decide whether the operator will be able to disengage the clutch or not. e) If your decision is "no". Is there any other geometric or material solution for the cone clutch mechanism? Electric Motor Gearbox Spring Shifting gra
