🔍 Key Concepts

• Force = Pressure × Area in pneumatic systems • How a diaphragm actuator converts air pressure into linear force • Which surface in the illustration actually has air pressure applied to it

💭 Think About

• Look at where the air pressure is applied in the actuator: which part has air on one side and the spring on the other? • Ask yourself: when pressure increases, which surface moves to compress or extend the spring? • Among the choices, which one clearly represents a surface area that air can push on?

✅ Before You Answer

• Identify in the figure which component separates the air chamber from the spring chamber and is flexible. • Confirm which part’s area is exposed to the air pressure, not just touching the spring mechanically. • Make sure the thing you select is a pressure-receiving surface, not a spring property like coil count or tension rating.
