Question

I can't seem to figure out this one every time I try a new approach I just come up with awnsers that are just way too big to right can you help me out with this?

**Problem Statement:**

Determine the magnitude of the couple force \( F \) so that the resultant couple moment on the crank is zero. [Figure 1]

Express your answer to three significant figures and include the appropriate units.

**Input Fields:**

- \( F = \) [Value] [Units]

**Diagram Explanation:**

The diagram features a crank system with forces and dimensions indicated:

- Two 150 lb forces are applied at angles of 30° relative to the horizontal lines of the crank.
- The crank has two segments:
  - The left segment is 5 inches long and inclined at a 30° angle downward from the horizontal.
  - The right segment is composed of a 5-inch section followed by a 4-inch vertical section, with an overall inclination from the horizontal.
- A force \( F \) and its opposite \(-F\) act at the ends of the segments, perpendicular to the segment inclined at 45°.
- Key dimensions include two segments measuring 5 inches each and a vertical segment of 4 inches.

The problem requires calculating the force \( F \) such that the couple moments around the crank result in equilibrium.
