Question

Two couples act on the beam (Figure 1).

Part A

If F = 175 lb, determine the resultant couple moment.
Express your answer to three significant figures and include the appropriate units.
**Figure Explanation** This diagram depicts a horizontal beam secured at one end to a wall. The beam is divided into segments illustrating various forces and dimensions: - **Dimensions:** - The beam is 2 feet long from the wall to the point where a downward force is applied, labeled as 200 lb. - From this point, an additional segment of 1.5 feet extends to another section where an upward force is applied. - At the end of the beam, there is a length of 1.25 feet where dual forces are applied at angles. - **Forces:** - A horizontal force of 200 lb acts leftward at the junction of the 2-foot and 1.5-foot segments. - Another 200 lb force acts rightward at another point along the beam. - At the end of the beam, two forces labeled "-F" and "F" are depicted at 30-degree angles to the horizontal axis, slanting upwards and downwards respectively. This setup illustrates the equilibrium of forces and moments acting on the beam, ideal for studying static equilibrium and mechanical engineering principles.
