There are three cylinders of the same volume on the table: the first is made of aluminum (2700 kg / m 3), the second is made of copper (8900 kg / m 3), the third is made of steel (7800 kg / m 3). Which cylinder exerts the most pressure on the table?

The greatest pressure is exerted by a copper cylinder. Since pressure depends on force and area, and the area of all cylinders is the same, we must pay attention to the force. The force depends on the mass and the acceleration of gravity. Since the acceleration of gravity is the same throughout the Earth, and mass depends on density and volume, a cylinder with a higher density will exert more pressure.
Answer: 2) a copper cylinder.
