plz provide answer for part c ques4 4. (a) Using fewer than 100 words, explain why passenger cars pow-ered by internal combustion engines need to have multiple gearratios.(Marks will be deducted for answers longer than 100 words)(b) An automotive clutch driven plate is clamped between a fly-wheel and a sprung pressure plate. The outer diameter of thefriction lining is 300mm, the inner, 250mm, and the coefficientof friction between the friction lining and the cast iron of the fly-wheel and pressure plate is 0.3. The maximum torque of the en-gine is 310N m and the maximum power of the engine is 210KW.Using a factor of safety of 1.2, calculate the minimum clampingforce to prevent slipping.(c) The type of pressure plate chosen as a result of the calculationin part (b) of this question applies a force of 4750N (note; this isNOT the correct answer for part (b)).i Calculate the applied pressure on the clutch linings.ii Using 100 words or fewer, and using calculations as required,describe the engineering changes to bring the clamping pres-sure below the manufacturer's limit, 0.2MPA, making surethe clutch still has the required torque capacity. Describe anydisadvantages implied by your chosen engineerina changes.
