Hi, first time poster.(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to calculate the clutch torque output using the following formula:

torque = force (450KG ((pressure plate calculated force) x gyration radius ( 0.09 Metres (( square root of inner radius squared x outer radius squared divided by 2) x coefficient of friction ( .30) x 2 (number of surfaces.

When i do the calculation the answer I get is 83.4- this has to be wrong. If i do the same calculation but with imperial values ( 950lb x 0.3 ft x 0.3 CF x 2 surfaces) I get 142ft lb, which equals 192Nm.

Is my error using kg when i should be using newtons? If so, I'm still baffled as to how to solve this. Apologies if this is a basic question.

Thanks in advance for any help.
