Two cylinders P and Q has a diameter of 100 mm and 180 mm respectively and weighs 200 N and 500 N respectively. If the bottom width of of the box where the two cylinders are fitted is 180 mm, withTwo cylinders P and Q has a diameter of 100 mm and 180 mm respectively and weighs 200 N and 500 N respectively. If the bottom width of of the box where the two cylinders are fitted is 180 mm, with one side vertical and the other inclined at 60°, determine the pressures at all the four points of contact.
