Theory of Machine In a reciprocating steam engine, when the crank has turned from inner dead centre through an angle θ, the angular velocity of the connecting rod is given by ω cosθ/(n² - sin²θ)1/2 ω sinθ/(n² - sin²θ)1/2 ω sinθ/(n² - cos²θ)1/2 ω cosθ/(n² - cos²θ)1/2 ω cosθ/(n² - sin²θ)1/2 ω sinθ/(n² - sin²θ)1/2 ω sinθ/(n² - cos²θ)1/2 ω cosθ/(n² - cos²θ)1/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ + S₂) / h (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / 2h (S₁ + S₂) / h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, if a spring of greater stiffness is used, then the governor will be Unaffected of sensitivity Isochronous More sensitive Less sensitive Unaffected of sensitivity Isochronous More sensitive Less sensitive ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of action of cam is defined as the angle Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Kinematic pairs are those which have Surface contact between the two elements when in motion Elements of pairs not held together mechanically Two elements that permit relative motion Point or line contact between the two elements when in motion Surface contact between the two elements when in motion Elements of pairs not held together mechanically Two elements that permit relative motion Point or line contact between the two elements when in motion ANSWER DOWNLOAD EXAMIANS APP
