Q6a)A block overlying a 10° wedge on a horizontal floor and leaning against a vertical Wal weighing 1500 N'is to be raised by applying a horizontal force to the wedge. Assuming the coefficient of friction between all the surfaces in contact to be 0.3,determine the minimum horizontal force to be applied to raise the block. b)The frustum of a solid cone has base diameter 10 cm and the top diameter 5 cm and height 7.5 cm. Determine the centre of gravity of the solid.
