Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only All of these The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only All of these The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another 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 In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will not occur Will change Will remain same Could change or remain unaltered depending on which link is fixed Will not occur Will change Will remain same Could change or remain unaltered depending on which link is fixed ANSWER DOWNLOAD EXAMIANS APP
