Why is air pressure important to force?
Possibly. It depends on what you are designing. Generally, air pressure is equalized thoughtout a structure such as a house or something like a car. If you are designing something that is sealed then the outside pressure can be different from the internal pressure.
Why didn't the pickle jar pop when it was opened?
The pickle jar didn't pop when it was opened because the pressure inside the jar was equalized with the pressure outside, preventing the popping sound.
What is the structure that allows equalization of the pressure in the middle ear with that outside the body?
The Eustachian tube, nowadays known as the pharyngotympanic tube. THis structure connect the middle ear to the oropharnx allowing the air from outside into the inner ear, equalizing pressure and so reducung stress on the tympanic membrane. The tube is only open when the person is swallowing and this is why chewing gums on descending and ascending planes helps ears to "pop"
What is a force that acts from the outside of a structure?
An example of a force that acts from the outside of a structure is wind force. Wind can exert pressure on the exterior surfaces of a structure, causing stress and potential damage if not properly accounted for in the design and construction.
What is differential air pressure?
Differential air pressure is a term of comparison. It may be stated as "the difference in air pressure between..." and finished from there. Let's look at a sentence and then break it down. "The differential air pressure across the body of the 747 is a cause of concern over the life of the aircraft." A jet at altitude has a pressurized cabin. The outside air pressure is very low. (Think Mount Everest. Almost no one climbs it without suplimental oxygen.) There is a difference between the air pressure inside the cabin and the air pressure outside the cabin. This is an instance of differential air pressure. The differential air pressure puts stress on the body of the plane. When the aircraft is back on the ground, the differential pressure disappears. The alternating application and neutralization of stress across the hull damages the structure over the life of the airframe. The differential pressure is the difference between the pressure of the air in the (pressurized) cabin at altitude and the pressure of outside air at that altitude.
What is the term for the difference between the pressures inside and outside a tire?
The term for the difference between the pressures inside and outside a tire is called "tire pressure differential."
What is the difference between in the ground and on the ground?
In simplest terms, an above ground pool is built the handle the water pressure exerted from the inside but not the pressure of the ground around the outside. It takes the special structure of a pool built for burial in order for it to not collapse when placing it into the ground and backfilling.
What is the difference between the pressure inside and outside a tornado funnel?
The pressure inside a tornado funnel is lower than the pressure outside. This pressure difference is a key factor in the formation and strength of tornadoes, as the low pressure inside the funnel contributes to the destructive force of the winds associated with tornadoes.
What is the difference between the pressures inside and outside a bicycle tire called?
The difference between the pressures inside and outside a bicycle tire is called tire pressure differential.
What is inner structure?
An Internal Structure is the way an organism looks on the outside and an External Structure is the looks on the outside.
Is glass tough?
no it isn't flexible and that's a fact [Edited by 0siris] Some glass is made to be slightly flexible. In skyscrapers for instance, they make the window panes ever so slightly flexible so that when the pressure inside the building is equalized with the pressure outside the glass doesn't break.
When you are landing in an airplane does the air pressure increase or decrease?
It increases. In an unpressurized airplane, the pressure increases because the air is denser at lower altitudes. In a pressurized airplane, the pressure increases both because the pressure must be equalized before the doors can open and because the hull is not designed to withstand an outside pressure higher than the inside pressure.
