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) l₁l₂ = kG² l₁ = kG l₂ = kG l₁l₂ = kG l₁l₂ = kG² l₁ = kG l₂ = kG l₁l₂ = kG ANSWER DOWNLOAD EXAMIANS APP
