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 also +ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is -ve a is +ve and b is also +ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is -ve ANSWER DOWNLOAD EXAMIANS APP
