Topic: Fluid Mechanics
When a body floating in a liquid is given a small angular displacement, it starts oscillating about a point known as
- A. centre of gravity
- B. centre of pressure
- C. metacenter
- D. centre of buoyancy
Answer: C. metacenter
Explanation: When a body floating in a liquid is subjected to a small angular displacement, the center of buoyancy shifts. The body starts oscillating about a theoretical point of intersection between the new vertical line of buoyant force and the original vertical axis. This point is known as the metacenter (M).
