Theory of Machine The acceleration of a particle at any instant has two components i.e. radial component and tangential component. These two components will be Inclined at 45° Parallel to each other Opposite to each other Perpendicular to each other Inclined at 45° Parallel to each other Opposite to each other Perpendicular to each other ANSWER DOWNLOAD EXAMIANS APP
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 + 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)} ANSWER DOWNLOAD EXAMIANS APP
