In the last system – a 30 ml. piston connected to a 60ml. piston – the pressure of the fluid in the pistons is the same (Pascal’s Law)
However, the diameter of the 30ml. piston is 1” and of the 60ml. is 1¼”
Estimate the mechanical advantage of using the larger piston by feeling the forces involved
Calculate the difference between the forces acting in and on the plunger of each piston?
