Q2) A loaded Porter governor has four links each 200 mm long and are hinged at a distance of 40 mm from the axis of rotation. The mass of each ball is 2 kg and mass of the sleeve is 20 kg. The governor sleeve begins to rise at 300 r.p.m. when the links are at an angle of 35° to the vertical. Assuming the friction force to be constant, determine the minimum and maximum speed of rotation when the inc lination of the arms to the vertical is 40°.
The rotor of an electric motor has an angular velocity of 4500 rpm when the load and power are cut off. The 75-kg rotor, which has a centroidal radius of gyration of 200 mm, then coasts to rest.
