Force = 450N
Area Of Contact = 5m * 4m = 20m2
Pressure = Thrust /Area = 450/20 N/m2 = 22.5 PA = 22.5 N/m2
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
That's the definition of the 'pressure' which the force exerts on the surface.
No, that is not true. Pressure has the dimension of force/area, which is not the same thing as just force.
Pressure equals force/area so from this you can get area equals force/pressure. plug in your numbers and get an area of 3. I'll let you work out the units
The area around electrons that exerts a force is an electric field. :)
yes, force divided by area is pressure; its units are pounds per square inch, or newtons per square meter, for example. I you pull on an object with force over an area it is called stress
Pressure is measured by the force it exerts on an area. Usually pounds per square inch (psi) or newtons per square meter ( called Pascals ). To find the pressure of a gas you need to know how much force it exerts over a certain area. This is usually accomplished with a pressure gauge.
It exerts pressure downwards unlike liquids. In short the pressure is weight/area
It is if a brick rests on a table the force with which the brick pushes on the table is its weight. The pressure it exerts on the contact area depends on the brick's orientation. If the contact area between brick and table is larger, the brick exerts less pressure on the contact area.
tiptoesWhen standing on tiptoe, the force exerted by your body remains the same, but is now concentrated in a smaller area. Pressure is measured in force divided by area. By reducing the area, you increase the pressure.
Force = Area*Pressure 1 Pascal = 1 N/m^2 1500N = Area*500Pa Area = 1500N/500Pa = 3m^2
This is because, same force acting on a smaller area exerts a larger pressure and smaller pressure on larger area. Here, buildings are given wide bases to exert less pressure on large area.
