On the small piston with area s = 25 cm² at a hydraulic press se
press with force f = 10N. Knowing that the big piston of the press raises a body with
mass of 100 kg, find the area (S) of the large piston of the hydraulic press.
Give g = 10 N / kg.

none, its a machine

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
