Write a note on Pascal's discovery in helping to make hydraulic jacks.

Explanation

Pascal's principle :
External pressure applied to abn enclosed body of fluid is transmited equally in directoion throughout the fluid volume and the walls of the containing vessel.
Use :
1. Thes principle is used in desinging and working of hydraulic jacks.
2. Hydraulic jacks are useful to lift heavy objects like cars and other vehicles in automobile work shops when the vehicles are to be required or repaired.
3. Here very less force is used to lift such heavy vehicles.
Appreciation :
1. Hydraulic jacks are used not only in automobile work shops, but also in so many
2. All the comforts which we are enjoying now are the efforts of scientists who discovered the laws and principles.
3. Hence we have to appreciate the efforts of Pascal for his contribution in desingning these principles.
