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) I ω ωP Iω² (1/2). I ω ωP (1/2).Iω² I ω ωP Iω² (1/2). I ω ωP (1/2).Iω² ANSWER DOWNLOAD EXAMIANS APP
