torque transmitted by a clutch

[kevcrow]

Having had all my files stolen, would be very grateful if someone could supply equation to calculate the torque transmitted by a multiplate motorcycle clutch. many thanx

I don't know much about motorcycles, but the torque transmitted by a multiplate friction clutch assuming the uniform wear theory is n*mu*P*(r1+r2)/2 where n is the number of friction surfaces, mu is the coefficient of friction, P is the axial force, and r1 & r2 are the outside and inside radii of the friction surfaces. Hope that helps.
