f finding this coefficient withoutmeasuring either P or F. It makes use of an inclinedplane and the parallelogram of forces. In Fig. 55 0 is supposed to be a body resting upon theincline AB, which is just steep enough to keep 0 movingwith uniform velocity, in spite of friction, if it is oncestarted… … Fig. 55. causes the friction. It is the force OM that maintainsmotion in spite of the friction. If the body moves with uniform velocity down theincline, as we have supposed, the force OM must be exactlyequal and opposite to the resistance of friction. For if OMwere greater than the friction, the…
