What does a pneumatic cylinder primarily do?

A pneumatic cylinder primarily converts energy into force, and in this case, it uses compressed air as the source of energy to create linear motion. When compressed air is supplied to one side of the cylinder, it generates pressure that pushes a piston, which in turn creates mechanical force. This process is crucial in various applications where linear actuation is needed, such as in automation systems, material handling, and robotics.

The correct answer highlights the fundamental functionality of pneumatic cylinders in industrial contexts, where their ability to exert force is harnessed for tasks that require movement or positioning. The conversion of energy into force allows for the effective operation of machines and devices that rely on pneumatic systems for efficiency and power.
