&3 … the pulley B will move through a distance 2(h) ~\-h.Similarly, the motion of A will be through a distance2(2h + h) + h9 and the distance (= s) for P =2(2A + 2A + A) + A = 15, or (2* - l)ft. ThereforeWh = (2* - 1)A.P, and W = (2*-l)P; or, in gene-ral, TT = (8- - 1)P. 226. Application of the Pulley.…
