Given below are two quantities named I and II. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose among the possible answers. A man has two balls. The ratio of radius of first ball to that of the second ball is 7 : 3. Quantity I: If man cut the first ball from middle and difference between total surface area of part of first ball and total surface area of second ball is 1538.46cm2, then find the radius of smaller ball. Quantity II: If the sum of radius of two balls is 30, then what is the radius of first ball?

Ball bearings are preferred over other types of bearings for machines rated up to 75 kW. Which of the following is not true for ball bearings?
The layout of a shaft supported on bearings at A & B is shown. Power is supplied by means of a vertical belt on pulley B which is then transmitted to pulley C carrying a horizontal belt. The angle of wrap is 180’ and coefficient of friction is 0.3. Maximum permissible tension in the rope is 3kN. The radius of pulley at B & C is 300mm and 150mm. If allowable shear stress in the shaft is 70N/mm² and torsional and bending moments are M=1185000N-mm and m=330000N-mm, find the diameter of the shaft.
