Part A

Determine the magnitude of the moment of the force F={50i− 25 j − 80k}N about the base line AB of the tripod. (Figure 1) Express your answer to three significant figures and include the appropriate units.

**Transcription and Analysis of the Geometric Figure**

This diagram depicts a three-dimensional pyramid structure with a square base on an x-y plane. The pyramid is formed by connecting four triangular faces: triangles ADB, ABC, BCD, and CDA. The apex of the pyramid is labeled point D, and the base vertices are labeled A, B, and C.

**Dimensions and Measurements:**

- The height of the pyramid (from the base to the apex D) is 4 meters.
- The horizontal distance from A to B is 2.5 meters.
- The horizontal distance from B to C is 1.5 meters.
- The horizontal distance from C to D is 2 meters.
- The vertical drop from point F to the top of the pyramid (point D) is represented with a vector, suggesting a possible application of force, indicated as F.

**Base of the Pyramid:**

- The square base is measured as follows: 
  - AB = 2.5 m on the y-axis.
  - BC = 1.5 m on the x-axis.
  - CD = 2 m connecting C and D horizontally.
  - DA = 4 m vertically from point A.

This geometric figure is likely used in physics or engineering contexts to illustrate concepts such as forces acting on structures, stability analysis, or three-dimensional space visualization.
