Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor 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 (cos 2θ/n) m.ω².r cosθ m.ω².r sinθ m.ω².r (sin 2θ/n) m.ω².r (cos 2θ/n) m.ω².r cosθ m.ω².r sinθ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm ANSWER DOWNLOAD EXAMIANS APP
