Classification of types of corrosion

Corrosion is described as the process in which a certain element is degraded or deteriorated due to the presence of multiple chemicals in the surrounding. Generally, corrosion happens if all the subatomic particles on a metallic object are oxidized, for example, rust on iron structures. In air or water, metals lose electrons to other particles (like oxygen), leading to the formation of an oxide with the metal.

**Required Information**

The helium-filled balloon in the image is tethered at 20°C and 1 atm with a string of negligible weight and drag. The diameter is 44 cm, and the balloon material weighs 0.2 N not including the helium. The helium pressure is 120 kPa.

---

**Diagram Explanation:**

The diagram shows a helium-filled balloon tethered to a surface. The balloon is subject to an airstream labeled as having velocity \( U \). The tether forms an angle \( \theta \) with the vertical. The diagram indicates:

- \( U \): Airstream velocity directed horizontally.
- \( \theta \): Angle between the tether and the vertical, to be estimated.
- \( D \): Diameter of the balloon, 44 cm as specified.

---

**Problem Statement**

Estimate the tilt angle \( \theta \) if the airstream velocity \( U \) is 28 m/s. Assume a drag coefficient of 0.2.
