In summary, the distance the piston head will move when a certain force is applied to a cylinder with a cross section area of pi*d^2/4 (where d is the diameter of the cylinder) depends on the contents of the cylinder. If the cylinder is filled with concrete, an incompressible liquid, or vacuum, the piston will not move or will burst. If there is compressible gas inside the cylinder, the distance the piston will move cannot be determined without more information.

racool said:i got a small doubt.. can any1 please xplain me. if we apply a certain force"F" on cylinder of area of cross section A=pi*d^2/4(thatis,the diameter of cyllinder is d),then how much distance will the piston head move ??
It depends on what's inside the cylinder.
- If we've packed the cylinder of concrete and allowed it to harden, the piston won't move at all, no matter how much force we apply.
- If the cylinder has no leaks and is full of an incompressible liquid, the piston won't move but the cylinder will burst if we apply enough force.
- If there's nothing in the cylinder at all, just vacuum, any force at all will cause the piston will move all the way to end of the cylinder
- If there is some compressible gas in the cylinder...
If you could clarify your question you'll get better answers.
FAQ: Piston and Cylinder: Force, Area, Distance
What is a piston and cylinder?
A piston and cylinder is a mechanical device that consists of a cylindrical chamber (cylinder) with a movable part (piston) that can move back and forth inside the cylinder. It is commonly used to convert fluid or gas pressure into mechanical force.
How does a piston and cylinder work?
A piston and cylinder work based on the principles of fluid mechanics. When a fluid or gas is compressed into the cylinder, it exerts pressure on the surface of the piston, causing it to move. The movement of the piston generates a force that can be used to perform work.
What factors affect the force produced by a piston and cylinder?
The force produced by a piston and cylinder is affected by three main factors: the applied pressure, the surface area of the piston, and the distance the piston travels. The greater the pressure, surface area, and distance, the greater the force produced.
How is force calculated in a piston and cylinder system?
The force produced by a piston and cylinder can be calculated using the formula F = P x A, where F is the force, P is the pressure, and A is the surface area of the piston. This formula is based on the principle that force is directly proportional to pressure and surface area.
What is the relationship between the piston diameter and the force produced?
The force produced by a piston and cylinder is directly proportional to the surface area of the piston. This means that the larger the diameter of the piston, the greater the surface area and the more force it can produce. However, the pressure applied also plays a role in determining the force, so a larger diameter does not always mean a greater force if the pressure is low.
