Theory of Machine Angle of ascent of cam is defined as the angle During which the follower returns to its initial position 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 highest position Of rotation of the cam for a definite displacement of the follower During which the follower returns to its initial position 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 highest position Of rotation of the cam for a definite displacement of the follower 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 R/2 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 ANSWER DOWNLOAD EXAMIANS APP
