🔍 Key Concepts

• Bourdon tube operation – internal pressure acts on the walls of a curved tube and makes it tend to straighten. • Pressure vs. force – recall that pressure is force per unit area: ( P = \frac{F}{A} ). • Inner vs. outer arc of a curve – the outer arc is longer, so it has more surface area exposed to the same internal pressure.

💭 Think About

• In a sealed tube filled with fluid at one pressure, is the pressure different between the inner and outer sides of the same cross‑section, or is it the same everywhere? How does that affect which options mentioning pressure can be correct? • If the pressure is the same on both arcs, what must be different (between arc AB and arc DC) to create a net straightening effect? • Look at the illustration: which arc (AB or DC) is on the outside of the curve and therefore has the larger area for the same pressure to act on? What does that imply about the total force on that arc?

✅ Before You Answer

• Confirm that pressure inside the tube is uniform and does not depend on whether you are on the inner or outer side of the bend. • Use ( P = \frac{F}{A} \Rightarrow F = P \times A ) to reason about how equal pressure can still create different forces on different arcs. • Verify from the figure which labeled arc (AB or DC) is the outer radius of the curved Bourdon tube and therefore experiences the greater total force.
