Question
(a)
State the main advantages of toothed clutches.
(b)
Uniform wear theory is used in designing a new friction clutch. Explain your ideas
and concepts to support the statement.
(c)
(d)
A brand new Street Performace Clutch are capable to delivered 135 Nm torque when
the engine's flywheel is rotating at 1400 RPM. The other technical specifications are
describe in Table (c). Over the years, the clutch torque performance had reduced to
100 Nm due to wear and tear of the ceramic plate while the others specification was
remained unchanged.
(i) Assuming the steel plate were made to wear resistance. Examine how much has
the ceramic plate worn off on each contact surface individually.
(ii) Calculate the transmission power lost in kW.
