Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at 45° in the direction opposite to the rotation of the link containing the path 45° in the direction of rotation of the link containing the path 90° in the direction of rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 45° in the direction of rotation of the link containing the path 90° in the direction of rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system of masses rotating in different parallel planes is in dynamic balance if the Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero Resultant force is equal to zero Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero Resultant force is equal to zero ANSWER DOWNLOAD EXAMIANS APP
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 2R Become equal to R/2 Remain same as before Become equal to R/4 Become equal to 2R Become equal to R/2 Remain same as before Become equal to R/4 ANSWER DOWNLOAD EXAMIANS APP
