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) / 2h (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / h (S₁ - S₂) / 2h (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be One fourth of the first one One and a half times the first one Four times the first one Same as the first one One fourth of the first one One and a half times the first one Four times the first one Same as the first one ANSWER DOWNLOAD EXAMIANS APP
