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 One lower pair and two additional links Two lower pairs and two additional links Two lower pairs and one additional link Any one of these One lower pair and two additional links Two lower pairs and two additional links Two lower pairs and one additional link ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a steam engine, the earlier cut-off with a simple slide valve may be obtained by increasing the steam lap and the angle of advance of the eccentric but keeping constant the travel and lead of the valve, this method will All of the listed here Reduce length of effective stroke of piston Cause withdrawing or throttling of steam Reduce maximum opening of port to steam All of the listed here Reduce length of effective stroke of piston Cause withdrawing or throttling of steam Reduce maximum opening of port to steam 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 sinθ m.ω².r (cos 2θ/n) m.ω².r (sin 2θ/n) m.ω².r cosθ m.ω².r sinθ m.ω².r (cos 2θ/n) m.ω².r (sin 2θ/n) ANSWER DOWNLOAD EXAMIANS APP
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 not occur Will remain same Will change Could change or remain unaltered depending on which link is fixed Will not occur Will remain same Will change ANSWER DOWNLOAD EXAMIANS APP
