Why is CLUTCH Required?
IC engines develop low torque at starting speed and as the speed increases, develop enough torque to pick up the load.
E.g. if the power from a running engine is transmitted to the drive wheels when the truck is at stand still
The truck will jump out if the power is too large.
The engine will stop or stall if the power is too small.
