Theory of Machine Cam angle is defined as the angle During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower Through which, the cam rotates during the period in which the follower remains in the highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower Through which, the cam rotates during the period in which the follower remains in the highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is also +ve ANSWER DOWNLOAD EXAMIANS APP
