Each tire supports 2100 N, and the pressure exerted by each tire is 20 N per centimeter2, so Pressure = Force / Area Pressure = 20 N per centimeter2 Force = 2100 N rearranging the equation for Area Area = Force / Pressure Area = 2100 / 20 = 105 centimeter2 So each tire has 105 cm2 touching the road.

How much atmospheric pressure is exerted on one square inch of earth?
14.7 pounds. Atmospheric pressure is 14.7 pounds per square inch Keep in mind that unless air is trapped you do not feel this as pressure is equalized

What if your weight is less on the moon than it is on the Earth why so?
Weight is the gravitational force exerted on an object. Your mass is the same on earth and the moon or anywhere else. Your weight depends on the gravitational force exerted on your mass and hence on your location.
Calculate the area of a 1500n object that exerts a pressure of 500pathen calculate the pressure exerted by the same object over twice that area?
3m2
Why does building foundations have a large horizontal area of contact with the ground?
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
How do you calculate force for hydraulics?
You get the force exerted by a hydraulic piston by taking the pressure times the surface area of the piston.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a liquid or a gas?
The pressure exerted by a solid object is in only one direction.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a gas or liquid?
The pressure exerted by a solid object is in only one direction.
What is the lowest pressure exerted by blood in your arteries is your- blood pressure?

Why is pressure exerted from all directions in water?
Because the pressure is exerted throughout the body of water.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is the force exerted on surface divided by the area over whech the force is exerted?
That's the pressure on that particular area.
