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 A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to I₂/G G.I₂ G².I₂ I₂/G² I₂/G G.I₂ G².I₂ I₂/G² ANSWER DOWNLOAD EXAMIANS APP
