Question
# Diagram Explanation The diagram illustrates four forces, labeled A, B, C, and D, represented as vectors originating from a common point. The angles between the vectors are marked to illustrate their directions in the plane: - **Force A** (Red): Directed at an angle of 50° from the positive x-axis. - **Force B** (Blue): Directed at an angle of 75° from the negative y-axis. - **Force C** (Green): Directed at an angle of 55° from the negative x-axis. - **Force D** (Black): The direction of force D is indicated but its exact angle and magnitude are to be determined. # Solution Determine the magnitude and direction of force **D** required for equilibrium if the forces act in the directions shown and have magnitudes: - \( A = 20 \, \text{lbs} \) - \( B = 20 \, \text{lbs} \) - \( C = 60 \, \text{lbs} \) \[ D = \boxed{\phantom{0}} \] acting at an angle of \(\boxed{\phantom{0}}\) measured \(\boxed{\phantom{0}}\) from the \(\boxed{\phantom{0}}\).
