🔍 Key Concepts

• Bourdon tube pressure gauge construction (curved, flattened tube that tends to straighten when pressurized) • Difference between pressure (force per unit area) and total force (pressure × area over which it acts) • How curvature changes the inner vs. outer circumference areas when pressure acts inside a bent tube

💭 Think About

• When uniform internal pressure acts inside a curved tube, is the pressure itself higher on the inner or outer wall, or is it the same everywhere? • If pressure is the same everywhere, what makes one side of the tube experience a larger total force than the other? Think about which side has the larger surface area for the same angle of curvature. • Which side (inner or outer) will tend to stretch/straighten the tube when the larger total force acts there?

✅ Before You Answer

• Confirm that pressure inside the tube is uniform and does not depend on inner vs. outer radius for a static fluid or gas. • Visualize (or sketch) a small slice of the curved tube and compare the area of the inner wall vs. the outer wall for that slice. • Match the choice that mentions total force acting on the side (inner or outer) that would logically cause the tube to try to straighten.
