The weight of the shoes in the centrifugal clutch is G = 450 grams. The springs connecting the shoes to each other are placed symmetrically with respect to the drum center. The friction coefficient between the friction elements and the drum is μ = 0.25, while the rotating shaft in the middle reaches n = 850 rpm, the spring elastic force is defeated and when the clutch is fully engaged, the speed becomes n' = 1300 rpm. Evaluating the given, determine the spring force and clutch moment that must be overcome.
