The hydraulic oil in a car lift has a density of 8.30x10^2 kg/m^3. The weight of the input piston is negligible. The radii of the input piston and output plunger are 6.20x10^-3 m and 0.125 m, respectively. What input force F is needed to support the 27,000-N combined weight of a car and the output plunger under the following conditions? (a) The bottom surfaces of the piston and plunger are at the same level.(b) The bottom surface of the output plunger is 1.10 m above that of the input piston.

1a) Some are magnetic because of the orientations of their atoms (the magnetic ones have all their atoms lined in one direction). The other ones are disordered. 1b)Non-magnetic iron can be made magnetic by 'lining up' the atoms--one way is to stroke the material in one direction over and over with a magnetic material, which will realign the atoms.
