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 The essential condition of placing the two masses, so that the system becomes dynamically equivalent, is (where l₁ and l₂ = Distance of two masses from the centre of gravity of the body, and kG = Radius of gyration of the body) l₁ = kG l₂ = kG l₁l₂ = kG² l₁l₂ = kG l₁ = kG l₂ = kG l₁l₂ = kG² l₁l₂ = kG ANSWER DOWNLOAD EXAMIANS APP
