Question
**Title:** Replacing a Couple and Force with an Equivalent Single Force

**Problem Statement:**

Replace the couple and force shown by an equivalent single force applied to the lever. Determine the distance from the shaft to the point of application of this equivalent force.

**Diagram Explanation:**

- The diagram features a lever attached to a circular shaft at point \( O \).
- A force of 100 lb is applied vertically downward at a point \( B \) on the lever.
- An additional horizontal force of 50 lb is applied at a distance of 5 inches to the left of point \( O \).
- The lever makes an angle of \( 60^\circ \) with the horizontal, beginning from \( O \), extending \( 10 \) inches to point \( B \).
- The redirection line extends to the right of the lever, implying the horizontal component of force.

The goal is to calculate where the equivalent single force would act along the lever to produce the same mechanical effect as the current combination of forces and couple.
