The pressure P will be equal along the whole cord… … .-*-.. n<^i56 If we assume that the pressure P pulls the cord downwardsa distance of 12 in., then the pulley B and weight would beraised 6 in., because it would require 6 in. of each supportingcord to obtain the 12 in. of Ps movement. The space ratio orvelocity ratio would therefore be two. Fig.…
