SUMMARY

The discussion focuses on calculating the force transmitted by a clutch in a vehicle with an engine power of 30 horsepower (hp) operating at 3000 RPM. The formula used is power = torque * angular velocity, leading to a calculated torque of 52.5 ft.lbs using the equation 30 hp x (5252/3000 RPM). It is emphasized that the torque may not represent the peak torque of the engine, and the clutch design must include reserve capacity to prevent slippage under high loads.

PREREQUISITES
  • Understanding of basic mechanical engineering principles
  • Familiarity with torque calculations
  • Knowledge of clutch design and functionality
  • Experience with engine performance metrics
NEXT STEPS
  • Research the principles of torque and angular velocity calculations
  • Study clutch design considerations for high-load applications
  • Learn about engine torque curves and peak torque identification
  • Explore methods for calculating reserve capacity in clutch systems
USEFUL FOR

Mechanical engineers, automotive designers, and anyone involved in clutch system design and performance optimization.

hi, I'm designing a clutch and need to calculate the force transmitted by the clutch. engine power is 30hp and rpm is 3000. How to calculate.

You mean torque?

power = torque * angular velocity.

There may be peaks above that because of the non-constant torque produced by an engine.
 
OK thanks bro.
 
30 hp x (5252/3000 rpm) = 52.5 ft.lbs of torque.

As mentioned, that may not be the torque peak of the engine, and the clutch also needs reserve capacity in order to resist slippage when applying the clutch at high loads.
