Theory of Machine The ratio of height of Porter governor (when length of arms and links are equal) to the height of Watt's governor is (where m = Mass of the ball, and M = Mass on the sleeve) m/(m + M) (m + M)/m (m + M)/M M/(m + M) m/(m + M) (m + M)/m (m + M)/M M/(m + M) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A disc is a spinning with an angular velocity ω rad/s about the axis of spin. The couple applied to the disc causing precession will be (where I = Mass moment of inertia of the disc, and ωP = Angular velocity of precession of the axis of spin) Iω² (1/2).Iω² I ω ωP (1/2). I ω ωP Iω² (1/2).Iω² I ω ωP (1/2). I ω ωP ANSWER DOWNLOAD EXAMIANS APP
