Pressure
-
Pressure is continuous physical force exerted on or against an object by something in contact with it.
-
A block with lenght of p = 1.5 m, width l = 1 m, height t = 0.5 m and mass m = 300 kg lays on the table. What is the pressure at the bottom surface of the block?
-
Atmospheric pressure
Atmospheric pressure is the force per unit area exerted by the air that forms the atmosphere on the earth's surface.
: 
-
Calculate the pressure exerted by a brick that weighs 10N on horizontak surface, if the contact area is 0.01m2.
-
Pascals laws
-
Pressure applied to an enclosed fluid will be transmitted with the same magnitude to every point of the container.
-
-
Hydrostatic pressure
-
What is the pressure exerted by water over the bottom of a 10m 25m area, 1m deep, swimming pool? (What’re density 500 kg/m3)
