PRESSURE PROBLEMS I

2 .- Calculate the pressure exerted by a force of 100 N over an area of 2m2.

3 .- That pressure made on the screen a sewing needle that is pushed with a force of 40 N and has a section of 8.10 m2?

4 .- A bathyscaphe submerged in the ocean at a depth of 150 m. Calculate:

a) the pressure that exists at this depth (ocean water density = 1040 kg/m3)

b) The force that supports a built-in light of 40 cm in diameter

5 .- What pressure supports a Buzo submerged in the sea 10 meters deep. Water density = 1030 kg/m3

6 .- Calculate the pressure difference that exists between points A and B within a liquid of density 1200 kg/m3 are respectively 10 cm and 20 cm below the surface.

7 .- With a hydraulic press can get a force ten times higher than the employed. What can be said of the relationship between sections of the pistons?

8 .- The area of \u200b\u200bthe piston or plunger of a large hydraulic press is one hundred times larger than the small piston. Do you think the force that acts on the greater when it exerts on a small force of 50 N.

9 .- We need a hydraulic lift to lift a truck that weighs 20,000 N The lower section of the piston is 10 cm2, and the larger piston, 140 cm2. That we should apply force to the plunger small?
