What does the surface area of an object have to do with the amount of pressure it can exert?

It only has to do with the surface area in contact with the support force (the side or surface that is in contact with the ground, table, etc.). If you have two cans, each with 3 solid bricks on top of them. One can has a diameter of 3 cm, while the other has a diameter of 5 cm. Which one has greater pressure? The can with a diameter of 3 cm. This is because there is less surface area in contact with the support force, so there is less area to distribute the force. Pressure is inversely related to area. Remember that pressure is measured in Pascals. Pressure is equal to Force over Area or p=F/A.
Assuming that both cans have the same weight with the bricks on top. Lets assume each weighs 5 kilograms. So the pressure for the 5 cm can would be 5 kg (weight) * 9.8 (Gravity force) / 5 cm * pi (Area) or about 3.12 Pascals. Our 3 cm can would be 5 kg * 9.8 / 3 cm * pi or about 5.20 Pascals.

How do you convert mass to pressure?
mass / area although technically it should be weight (or force) / area for example: imperial an object with a mass of 1.5 lb and an area of 2 square inches will exert a pressure of 0.75 pounds per square inch (psi) metric an object with a mass of 1.5 kg and an area of 0.5 square metres will exert a pressure of 3 kg/m2 (or 3 N/m2 or 3 Pa)
How much does pressure does a one half inch diameter column of water exert at its base?
The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).
A column of water 2.31 feet high exerts a pressure of one pound per square inch How much pressure does a column of water 27feet 9inches exert?
12psi
What information do i need to find the force of an object?
An object, in itself, does not have any force. It can exert a force on another object, such as gravitational or electro-magnetic attraction or repulsion, or from impact. However, in all such cases, you require two (or more) objects: one object, in isolation, exerts no force.
A column of water 2.31 feet high exerts a pressure of one pound per square inch How much pressure does a column of water 27feet 9 iches high exert?
12.01 psi
Which of does the atmosphere exert pressure on?
the earths surface.
Which of these does the atmosphere exert pressure on?
the earths surface.
Why does the air exert pressure on the surface of the earth?
Air produces a force on the surface of an object (in this case the earth) because of the movement of the particles that make up air. This force over a defined area is known as pressure.
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
What kind of pressure does a column of air exert on the air or surface below it?
air pressure
Liquids and gases exert a buoyant force on object placed in them?
Yes, liquid and gases exert a buoyant force on object because of the surface tension of the fluid.
Is simple pump can exert a suficient amount of pressure for bike tire?
Yes
Why would a denser fluid exert stronger pressure on an object in the fluid than a less dense fluid would?
A denser fluid would exert stronger pressure on an object in the fluid than a less dense fluid would because of the pressure differences. A denser fluid would have a greater pressure difference, therefore greater buoyancy, and exerting stronger pressure on the object.
Which object does gravity exert a greater force on?
The one with the greatest mass that is closest to the surface of the Earth.
Which will exert more pressure river water or same amount of sea water?
Salt water is denser, and therefore will exert more pressure (for two columns of the same height).
What is the difference between altitude and air pressure?
Air pressure is the amount of pressure exerted by Earth's atmosphere in a specific place, while altitude is the vertical distance of an object or place from sea level. Air pressure decreases as altitude increases, since there is less atmosphere to exert pressure.
How come a lighter object can exert more pressure towards the ground then a heavier object?
By distributing the weight over a smaller area.
