Theory of Machine When the crank is at the outer dead centre, in a reciprocating steam engine, then the acceleration of the piston will be ω² r {(n - 1)/n} ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n + 1)/n} ω² r {(n - 1)/n} ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n + 1)/n} 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) (1/2). I ω ωP I ω ωP (1/2).Iω² Iω² (1/2). I ω ωP I ω ωP (1/2).Iω² Iω² ANSWER DOWNLOAD EXAMIANS APP
