Read: What is a Clutch? - Types of Clutches

Consider a plate or disc clutch

Let

I

ω

ω

ω = Common angular speed of shat A and Shaft B after engagement

According to the principle of conservation of momentum, Total momentum before clutch engage is equal to the total momentum of the clutch after clutch disc engagement.

IA ω

Common angular speed after engagement of clutch pressure plate

Total Kinetic energy before

Kinetic energy after clutch engagement

Put the value of ω into above equation,

Now the loss of energy during clutch engagement, E= E

🔗 Difference between Single Plate Clutch and Multi Plate Clutch

Condition I - The rotor attached and hence the shaft B at rest ω

Put these condition in equation (a), and equation (b) we get

Common angular speed after the clutch engagement,

Loss of kinetic energy

Condition II - If rotor B at rest (ω

Common angular speed after the clutch engagement,

Kinetic energy loss,
