Blocks A and B shown in the figure have masses of 5 kg and 10 kg respectively.If the pulley is treated as a 3 kg solid disk with a 15 cm radius, determine the acceleration of the block A. Disregard the rope mass and any slip on the pulley.Consider that the moment of inertia of the pulley is given by Ip = (1/2)mr² in which m is the mass of the pulley and r is of radius the pulley.
The arms of a Porter governor are each 250 mm long and pivoted on the governor axis. The mass of each ball is 5 kg and the mass of the central sleeve is 30 kg. The radius of rotation of the balls is 150 mm when the sleeve begins to rise and reaches to certain radius at maximum speed. The governor has radius that is 175 mm at mid position. The speed range of the governor is 38 rpm, and the increment in speeds is constant in the three positions. Find : (1) the friction of the load which existed at the sleeve, and (2) the governor radius at maximum speed. The friction is ignore in mid position only.
