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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to 2R Become equal to R/4 Become equal to R/2 Remain same as before Become equal to 2R Become equal to R/4 Become equal to R/2 Remain same as before ANSWER DOWNLOAD EXAMIANS APP
