Based on the data provided, the force that must be applied at the small piston is f = 1500 × 9.81 × 250/A.
Pascal's principle states that the pressure applied to an enclosedfluid is transmitted undiminished tp every portion of the fluid.
Mathematically:
f/a= F/A
where
Therefore:
f = Fa/A
Since the area of the large piston is not given
f = 1500 × 9.81 × 250/A
Therefore, the force that must be applied at the small piston is f = 1500 × 9.81 × 250/A.
