Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the Broken belt and its adjacent belts Broken belt All the belts There is no need of changing any one as remaining belts can take care of transmission of load Broken belt and its adjacent belts Broken belt All the belts There is no need of changing any one as remaining belts can take care of transmission of load ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The displacement of a flat faced follower when it has contact with the flank of a circular arc cam, is given by (where R = Radius of flank, r₁ = Minimum radius of the cam, and θ = Angle turned through by the cam) (R - r₁) (1 - cosθ) R (1 - sinθ) (R - r₁) (1 - sinθ) R (1 - cosθ) (R - r₁) (1 - cosθ) R (1 - sinθ) (R - r₁) (1 - sinθ) R (1 - cosθ) ANSWER DOWNLOAD EXAMIANS APP
