Explain the working of (i) hydraulic lift (ii) hydraulic breaks.

What principle/law explains the working of the hydraulic brakes in automobiles ?

Explain the working of hydraulic press by giving an example.

Explain the working of heart under: (i) Systole (ii) Diastole

Assertion: Pascal law is the working principle of hydraulic lift. Reason: Pressure =(thrust)/(area)

Give the uses of a hydraulic press.

In a liquid whose rho = 1000 kg/m^3 at a depth of 2km the value of (Delta V)/ V = 1.36% is given then find the ratio of (hydraulic stress)/(hydraulic strain). ( g = 9.8m/s^2 )

With the help of a labelled diagram, explain the working of hydraulic brakes.

Ac cording to Pascal's law, the increases in pressure at one point f enclosed liquid in equilibrium of rest is transmitted equally to all other points of the liquid and also to the walls of the container, provided the effect of gravity is neglected. Hydraulic lift and hydraulic brakes are based on this very law. Read the above passage and anser the following question : (i) How do hydraulic brakes work ? (ii) What are the implication of this law in day to day life ?
