Which is/are not the characteristics of the wet clutch in comparison of the dry clutch (a) Has more life (b) High torque transmitting capacity (c) High cost (d) High coefficient of friction?

Option 3 : (b), (d)

Explanation:

A wet clutch is fully immersed in engine oil. Oil is used as lubrication and cooling for the clutch. It is not visible as it is packed inside the engine casing.

The dry clutch is not immersed in an oil sink as in the case of a wet Clutch. It runs dry. This is visible as it is placed in an open cage attached to the engine.

The difference between dry and wet clutch are following below:

• A dry clutch has a higher coefficient of friction. In a wet clutch coefficient of friction is reduced due to oil.
• The torque capacity of a dry clutch is high as compared to the wet clutch of the same dimension.
• Heat dissipation is more difficult in the dry clutch. In a wet clutch lubricating oil carries away the frictional heat.
• Wear is less in the wet clutch as compared to the dry clutch.
• The engagement in the wet clutch is smoother than a dry clutch.
