Question

Select four examples of fluid or pneumatic power systems.

crane
dentist's chair
barber's chair
bulldozer
calculator
wheelchair

Answer 1

Four examples of fluid or pneumatic power systems are cranes, dentist's chairs, barber's chairs, and bulldozers. These systems apply Pascal's Principle to perform work efficiently, often using hydraulic mechanisms or a combination of pneumatic and hydraulic elements.

Step-by-step explanation:

Fluid and pneumatic power systems utilize the principles of hydraulics and pneumatics to perform work by exerting force through a liquid or gas, respectively. These systems can be found in various applications around us. Four examples of fluid or pneumatic power systems that are commonly encountered include:

• Crane - Uses hydraulics to lift and move heavy loads with precision.
• Dentist's chair - Often uses pneumatics for adjustable positions and hydraulics for stable lifting.
• Barber's chair - Typically hydraulically powered to adjust the height and position of the seat.
• Bulldozer - Relies on hydraulic systems to move dirt and other materials with its blade and ripper.

Each of these systems applies Pascal's Principle: in a fluid enclosed in a space, a change in pressure is transmitted undiminished in all directions. This principle is fundamental for hydraulic systems seen in applications such as automotive brakes and heavy machinery like bulldozers, which often use a motorized pump for most of the work.

Answer 2

Fluid or pneumatic power systems are used in various applications, such as cranes, dentist's chairs, bulldozers, and wheelchairs.

Step-by-step explanation:

Fluid or pneumatic power systems are widely used in various applications. Four examples of such systems include:

1. Crane: Cranes often use hydraulic systems to lift heavy loads, utilizing the force generated by the pressure of fluids.
2. Dentist's chair: Many dentist chairs are equipped with pneumatic systems that control their height and position.
3. Bulldozer: Hydraulic systems in bulldozers enable them to exert immense force for pushing or lifting heavy objects.
4. Wheelchair: Some modern wheelchairs incorporate pneumatic systems for easy adjustment and movement.
