betransmitted from a shaft making 400 r.p.m. to a second shaft 20ft. away, making 400 r.p.m. also, 28-in. pulleys and a 2%-in. singlebelt would be most economical. The cost curve in this case isalmost flat from the 20-in. pulley size to the 36th-in. pulley size 1084 MECHANICAL AND ELECTRICAL COST… … 8 10 12 !4 1& i6 20 22 24 26 26 30 52 34 56 3d 40 42 44rewKf^ Diameter of Pulley, Inches Fig. 2.
