= B2 ; it is a work-ing force for the body of mass M, but a resistance for M,hence the separate symbols for the numerically equal forces(action and reaction). Similarly, the friction at A is B3 = Bs; a resistance for M,a working-force for M. (In some cases, of course, frictionmay be a resistance… … Fig. 156. Fig. 157. Fig. 155. dicular to AA. In Figs. 156 and 157 we see W and Mfree, and their corresponding small rotations indicated. Duringthese motions the kinetic energy (K. E.) of each mass haschanged by amounts d(K. E.)^/ and d(K. ~E.)m respectively, andhence eq. (XV.) gives, for each free…
