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 = 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 a is +ve and b is also +ve ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The sum of the two masses is equal to the total mass of body The center of gravity of the two masses coincides with that of the body All of these The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The sum of the two masses is equal to the total mass of body The center of gravity of the two masses coincides with that of the body All of these ANSWER DOWNLOAD EXAMIANS APP
