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 = kG l₁l₂ = kG² l₂ = kG l₁ = kG l₁l₂ = kG l₁l₂ = kG² l₂ = kG l₁ = kG 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 G².I₂ I₂/G² G.I₂ I₂/G G².I₂ I₂/G² G.I₂ I₂/G ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, the lift of the sleeve is given by (where r₁ and r₂ = Max. and min. radii of rotation, x = Length of ball arm of the lever, and y = Length of sleeve arm of the lever) (r₁ + r₂) (y/x) (r₁ + r₂) (x/y) (r₁ - r₂) (x/y) (r₁ - r₂) (y/x) (r₁ + r₂) (y/x) (r₁ + r₂) (x/y) (r₁ - r₂) (x/y) (r₁ - r₂) (y/x) ANSWER DOWNLOAD EXAMIANS APP
