Pneumatic circuit Pneumatic circuit A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work. In the normal sense of the term, the circuit must include a compressor or compressor-fed tank. The circuit comprises the following components: In general, based on the application, a pneumatic cylinder is usually a single acting cylinder, where there is a single port in the cylinder and where cylinder extension is done by compressed air and retraction by means of open coiled spring. In double acting cylinders two ports both extend and retract by means of compressed air. The direction
Potential energy the negative of this scalar field so that work by the force field decreases potential energy, that is In this case, the application of the del operator to the work function yields, and the force F is said to be "derivable from a potential." This also necessarily implies that F must be a conservative vector field. The potential "U" defines a force F at every point x in space, so the set of forces is called a force field. Given a force field F(x), evaluation of the work integral using the gradient theorem can be used to find the scalar
