AI Thread Summary
To calculate the force transmitted by a clutch, the relationship between power, torque, and angular velocity is essential. For an engine with 30 horsepower at 3000 RPM, the torque can be calculated as 30 hp multiplied by 5252 divided by 3000 RPM, resulting in 52.5 ft.lbs of torque. It's important to note that this value may not represent the peak torque of the engine, as torque can vary. Additionally, the clutch design should incorporate reserve capacity to prevent slippage under high loads. Proper calculations and considerations are crucial for effective clutch performance.

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.
 
Engineering news on Phys.org
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.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
