Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Any one of these Two lower pairs and one additional link One lower pair and two additional links Two lower pairs and two additional links Any one of these Two lower pairs and one additional link One lower pair and two additional links Two lower pairs and two additional links ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The secondary 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 cosθ 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) ANSWER DOWNLOAD EXAMIANS APP
