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 = 0 and b is +ve a is +ve and b is -ve a is +ve and b is also +ve a is +ve and b = 0 a = 0 and b is +ve a is +ve and b is -ve a is +ve and b is also +ve a is +ve and b = 0 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation between the controlling force (Fc) and radius of rotation (r) for a stable spring controlled governor is Fc = a/r + b Fc = ar + b Fc = ar Fc = ar - b Fc = a/r + b Fc = ar + b Fc = ar Fc = ar - b ANSWER DOWNLOAD EXAMIANS APP
