Theory of Machine The relation between the controlling force (Fc) and radius of rotation (r) for a stable spring controlled governor is Fc = ar - b Fc = ar Fc = ar + b Fc = a/r + b Fc = ar - b Fc = ar Fc = ar + b Fc = a/r + b ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is said to be unstable when the controlling force Increases as the radius of rotation decreases Decreases as the radius of rotation increases Remains constant for all radii of rotation Increases as the radius of rotation increases Increases as the radius of rotation decreases Decreases as the radius of rotation increases Remains constant for all radii of rotation Increases as the radius of rotation increases ANSWER DOWNLOAD EXAMIANS APP
