🔍 Key Concepts

• Dry-type friction clutch behavior under load • Effect of engine RPM on engagement/disengagement shock and heat • Difference between engaging vs disengaging a clutch

💭 Think About

• Think about when the greatest heat and friction are created in a clutch: is it when you are connecting power, or when you are disconnecting it? • How does engine speed (idle vs high RPM) affect how violently the clutch surfaces contact each other when they are brought together? • Which combination of action (engage/disengage) and RPM would keep the clutch discs rubbing (slipping) against each other the longest under heavy load?

✅ Before You Answer

• Identify which operation actually transmits power through the clutch (engaging vs disengaging) • Compare how much relative speed there is between clutch plates at idle vs high RPM • Ask which listed habit would create the most heat and glazing/wear on dry friction discs over time
