**Text Transcription:**

A force F = 25 lb is applied to the handle of a socket wrench at point B, while a force N = 15 lb is applied to the head of the socket wrench at point A to tighten a bolt at point O. (a) Compute the resultant force and moment at point O. (b) Determine a wrench resultant and the coordinates of the point at which the line of action of the wrench passes through the x-y plane.

**Diagram Explanation:**

The image shows a three-dimensional representation of a socket wrench with coordinates labeled along the x, y, and z axes. The forces applied to the wrench are illustrated as vectors:

- Force F (25 lb) is shown as a red arrow applied at point B on the handle, directed perpendicularly upward along the y-axis.
- Force N (15 lb) is depicted as another red arrow at point A, angled slightly off the z-axis.

The diagram includes labeled distances:
- The distance from point O to point A (along the x-axis) is 7.5 inches.
- The distance from point A to point B (in the direction of force F) is 1.25 inches.

The diagram helps visualize how the forces are applied to the wrench and the spatial relationships that will affect the resulting torque and force analysis.
