Theory of Machine A point B on a rigid link AB moves with respect to A with angular velocity ω rad/s. The radial component of the acceleration of B with respect to A, is (where vBA = Linear velocity of B with respect to A) vBA × AB vBA /AB v²BA /AB v²BA vBA × AB vBA /AB v²BA /AB v²BA 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 minimum length of the coupler will be 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The velocity of piston in a reciprocating steam engine is given by (where ω = Angular velocity of crank, r = Radius of crank pin circle, θ = Angle turned by crank from inner dead center, and n = Ratio of length of connecting rod to the radius of crank) ωr [cos θ + (cos 2θ/n)] ω²r [sin θ + (sin 2θ/n)] ω²r [cos θ + (cos 2θ/n)] ωr [sin θ + (sin 2θ/n)] ωr [cos θ + (cos 2θ/n)] ω²r [sin θ + (sin 2θ/n)] ω²r [cos θ + (cos 2θ/n)] ωr [sin θ + (sin 2θ/n)] ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
