Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Could change or remain unaltered depending on which link is fixed Will change Will remain same Will not occur Could change or remain unaltered depending on which link is fixed Will change Will remain same Will not occur ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The primary unbalanced force due to inertia of reciprocating parts in a reciprocating engine is given by (where m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, θ = Angle of inclination of crank with the line of stroke, and n = Ratio of the length of connecting rod to radius of crank) m.ω².r (sin 2θ/n) m.ω².r sinθ m.ω².r (cos 2θ/n) m.ω².r cosθ m.ω².r (sin 2θ/n) m.ω².r sinθ m.ω².r (cos 2θ/n) m.ω².r cosθ ANSWER DOWNLOAD EXAMIANS APP
