Which type of energy can hydraulic and pneumatic systems typically store?

Hydraulic and pneumatic systems store pressure energy, which is the energy stored in fluids under pressure. In a hydraulic system, this energy comes from the pressurized liquid, typically oil or water, which can exert force and move components within machinery. Similarly, in pneumatic systems, compressed air is stored under pressure and can be used to perform work, such as moving cylinders or driving tools.

The ability to store energy in the form of pressure is fundamental to how these systems operate, enabling them to perform tasks that require significant force and precision. This stored energy can be released in a controlled manner to accomplish various functions, making these systems versatile in numerous applications, from industrial machinery to automotive systems.

The other types of energy mentioned do not accurately represent what is stored in hydraulic and pneumatic systems. Thermal energy involves heat, mechanical energy relates to physical movement, and electrical energy pertains to power sources, none of which align with the primary function of these systems.
