Theory of Machine The advantage of the piston valve over the slide valve is that in the former case Wear is less Power absorbed is less Both wear and power absorbed are low The pressure developed being high provides tight sealing Wear is less Power absorbed is less Both wear and power absorbed are low The pressure developed being high provides tight sealing ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 3(l - 1) - 2j n = (l -1) - j n = 4(l - 1) - 3j n = 2(l - 1) - 2j n = 3(l - 1) - 2j n = (l -1) - j n = 4(l - 1) - 3j n = 2(l - 1) - 2j ANSWER DOWNLOAD EXAMIANS APP
