(i) A force of 50kgf is applied to the smaller piston of a hydraulic machine. Neglecting friction, find the force exerted on the large piston, if the

diameters of the pistons are 5 cm and 25cm respectively.
(ii) The diameter of neck and bottom of a bottle are 2cm and 10cm respectively. The bottle is completely filled with oil. If the cork in the neck is pressed in with a force of 1.2kgf, what force is exerted on the bottom of the bottle?


In a hydraulic machine 
force on larger piston/force on smaller piston=area of larger piston/area of smaller piston
let force on larger and smaller piston be F and f respectively
diameters of larger and smaller piston are 25cm and 5cm respectively
