ing in various ways, buthave not dealt with the specialcase of bodies rotating uni-formly, such as we have in thecase of belt-driven pulleys. Referring to Fig. 54, suppose that there is a tension Tj lb. on the tight side of the belt, and a tension Tg on the slack side. If the pulley has a radius of… … Fig. 54. VELOCITY CHANGING IN DIRECTION 97 done against the tension T, = 2^rT,; therefore the result-ing work done on the pulley in one revolution = E = 2,rrTi-2,rrT2 = 2^r(Ti-T,) (10) Now suppose that the pulley makes N revolutions in1 min.; then the work done on the pulley in I min. = E xN =…
