Free undamped vibrations

Whenever an object/system displaces in either side of its equilibrium position with the help of an external/internal means, then the object/system moves regularly or randomly on both sides of its equilibrium position. This motion is called vibration. Generally, there are three types of vibration: longitudinal vibration, transverse vibration, and torsional vibration.

Question

### Problem Statement:

**4–31.** Determine the moment of the force **F** about point **P**. Express the result as a Cartesian vector.

### Diagram Explanation:

The diagram is a 3D representation displaying various distances along the x, y, and z axes with labeled points **P**, **O**, and **A**. The force **F** is represented as a vector in the illustration.

- Point **P** is located 2 meters above the xy-plane along the z-axis.
- The coordinates for point **P** are effectively expressed as (0, 0, 2).
- Point **O** is positioned at the origin (0, 0, 0).
- Point **A** is located in the xy-plane, with coordinates (3 m, 3 m, 0).
- The force **F** is acting on point **A**, defined as **F = [2i + 4j - 6k] kN**.
- Distances from **O** to **A** include 3 meters along the x-axis, 3 meters along the y-axis, and 1 meter along the z-axis downward from A.
- The line OA is aligned diagonally, making a vector in 3-dimensional space.

This setup visualizes how the force at point A affects the point P, allowing calculation of the moment using vector operations.
