Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only All of these A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only All of these A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work 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 = 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 n = 3(l - 1) - 2j n = (l -1) - j ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a D-slide valve Meyer's expansion valve Governor Flywheel D-slide valve Meyer's expansion valve Governor Flywheel ANSWER DOWNLOAD EXAMIANS APP
