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 (cos 2θ/n) m.ω².r (sin 2θ/n) m.ω².r sinθ m.ω².r cosθ m.ω².r (cos 2θ/n) m.ω².r (sin 2θ/n) m.ω².r sinθ m.ω².r cosθ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a Governor Flywheel Meyer's expansion valve D-slide valve Governor Flywheel Meyer's expansion valve D-slide valve ANSWER DOWNLOAD EXAMIANS APP
