6) Verify Pascal's law experimentally.
7) With the help of the given diagram answer the following questions.
i) Which principle is proved by the given diagram?
ii) State the principle
8) Name the devices based on Pascal's law.
9) If the area of the piston 'M' is 0.05m2 and that of 'P' is 0.15m2, what
force produces in ‘N' when 40N force is applied in piston ‘M‘ ?
10) The value of force and area of the pistons is shown in the given
diagram. According to the given information calculate area of piston 'Y'
and the force on the piston 'Z'.
11) What is hydraulic press?
12) Why liquid is used in hydraulic press?

diagram.
14) Write down the equation to solve numerical problem related to hydraulic
press with the meaning of the symbols used in the equation.
15) How can we prove that hydraulic press is an effort multiplier?
16) Write down any two practical use of hydraulic press.
17) If the cross sectional area of piston 'x' is 60cm2 , piston 'y' is 180 cm2
and effort of 40N is applied on ‘X' then how much load is needed on
piston ‘Y' to balance it.
