Theory of Machine In a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ + S₂) / h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ + S₂) / h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h 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 G².I₂ I₂/G² G.I₂ I₂/G G².I₂ I₂/G² G.I₂ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
