Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only 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 All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another ANSWER DOWNLOAD EXAMIANS APP
