Pressure is defined as force per area or P = F/A. So, if I push my hand against a wall with the force of 10 newtons, I am dispersing that 10 newtons over the area of my hand. If my hand is say 7in * 4 inches, that would give a total area of 28in^2. The pressure I am exerting on the wall would be P = F/A = 10 Newtons/(28in^2) = .36 N/in^2.
If instead of pushing the wall with my hand, I push a nail against the wall, I am now applying the same 10 newtons of force, but my area is a fraction of the size. Since A goes down, pressure will go up. So now, my area may be A = 0.1in^2. P = F/A= 10Newtons/(.1in^2) = 100 N/in^2.

How does pressure vary with respect to area and force?
Pressure is directly proportional to force and inversely proportional to area. This means that an increase in force applied to a given area will result in an increase in pressure, while spreading the force over a larger area will decrease the pressure. Mathematically, pressure = force / area.
How does pressure vary with force?
Pressure is directly proportional to force, according to the formula pressure = force/area. This means that as force increases, pressure also increases as long as the area remains constant. So, a greater force applied over the same area results in higher pressure.
What is the quantity of pressure?
Pressure is a measure of force applied over a specific area. It is usually measured in units such as pounds per square inch (psi) or pascals (Pa). The quantity of pressure can vary depending on the force applied and the area over which it is distributed.
What is the difference between pressure and stress?
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
Will anyone answer you what is the force that air exerts on a given area?
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.

Can solids cause pressure?
Yes, solids can exert pressure on the surfaces they come into contact with due to their weight or force applied. This pressure can vary depending on the amount of force exerted and the contact area with the surface.

How many pounds of pressure does it take to break a car side window?
Since it would probably be tempered glass, 100lbs. of pressure.
How does the walls reaction force vary as you vary the force you push it with?
This is to do with Newtons 3rd law of motion. To evey action there is an equal and opposite reaction. The wall's reaction force is a way of expressing the total force that is being applied on the wall. In order to calculate the reaction force you need to be able to apply calculations to correctly estimate the total force. FT= FR+ FA if FT = FA then the FR= FA Where R is reaction, A is applied, and T is toal force.
How much pressure can bone withstand?
Bones can withstand a considerable amount of pressure. On average, bones can withstand compressive forces of around 180 Mpa (megapascals) to 230 Mpa. However, this can vary depending on the type of bone and the direction of the force applied.
What is the force that a machine applies?
The force that a machine applies is typically generated by a motor or engine within the machine. This force is utilized to perform tasks such as lifting, moving, cutting, or shaping materials based on the design and function of the machine. The amount of force applied can vary depending on the machine's specifications and intended purpose.
How pressur is exerted by toggle clamps?
Toggle clamps exert pressure by using a mechanism that multiplies the input force applied to the handle. The pressure exerted can vary depending on the model and size of the toggle clamp, but they are generally designed to provide a strong and consistent clamping force to hold objects in place securely. It is important to check the specifications provided by the manufacturer for the specific clamps being used.
Is friction independent of the area of contact?
Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure. This is, however, an idealization and can break down in some instances.
