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 Slightly more than 95 mm 45 mm 95 mm Slightly less than 95 mm Slightly more than 95 mm 45 mm 95 mm Slightly less than 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is said to be isochronous when the controlling force Increases as the radius of rotation decreases Remain constant for all radii of rotation Increases as the radius of rotation increases Decreases as the radius of rotation increases Increases as the radius of rotation decreases Remain constant for all radii of rotation Increases as the radius of rotation increases Decreases as the radius of rotation increases ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a screw jack, the effort required to lift the load W is given by (where α = Helix angle, and φ = Angle of friction) P = W tan(α + φ) P = W tan(α - φ) P = W cos(α + φ) P = W tan(φ - α) P = W tan(α + φ) P = W tan(α - φ) P = W cos(α + φ) P = W tan(φ - α) ANSWER DOWNLOAD EXAMIANS APP
