g the time t^ occupiedby G in sinking a measured distance 5,, from rest. Suppose^^ = 5 sec. and s^ = 10 ft. At any instant during this motion, the tension in the cordbeing S, we have for the angular acceleration 0of AB, which is shown free in Fig. 97, takingmoments about axis 0, O-^K^Sa-Fr, . . .… … 9 84 NOTES AND EXAMPLES IN MECHANICS. Solving ior p, we would find it constant, as also S; hence Ghas a uniformly accelerated rectilinear motion, and AB a uni-formly accelerated angular motion. Therefore (with foot, pound,and second), since (from eq. (2), p. 54, M. of E.) s^ — \pf\ andhence ^ = 2^,…
