**ENGR 2301** **9.** The members of a truss are pin connected at joint O. Determine the magnitudes of \( F_1 \) and \( F_2 \) for equilibrium. Set \( \Theta = 60^\circ \). *Diagram Explanation:* The diagram for question 9 shows a joint O with multiple forces acting on it. There are four forces labeled around the joint: a vertical force of 5 kN pointing upwards, a horizontal force of 7 kN pointing to the left, \( F_1 \) acting at a downward angle from the horizontal, and \( F_2 \) acting at an upward angle. The angle between the horizontal and \( F_1 \) is labeled as 30°. **10.** Determine the magnitude and direction \( \Theta \) of F so that the particle is in equilibrium. *Diagram Explanation:* The diagram for question 10 shows a particle with three forces acting on it. There is an 8 kN force acting horizontally to the right, a 4 kN force acting vertically downward, and a third force (labeled as 5 kN) acting at an angle, which needs to be determined for equilibrium. **Answers:** 1-4: DCCD 5: \( 54 \, \text{N} \) 6: \( 60 \, \text{N} \) 7: \( R = 409 \, \text{N}, F = 504 \, \text{N}, P = 1099 \, \text{N} \) 8: \( F_{AB} = 478 \, \text{lb}, F_{AC} = 518 \, \text{lb} \) 9: \( F_1 = 1.83 \, \text{kN}, F_2 = 9.60 \, \text{kN} \) 10: \( F = 3.96 \, \text{kN}, \Theta = 82.2^\circ \) --- This text describes exercises involving equilibrium of forces in a truss and a particle, along with diagrams for visual reference. The answers section provides calculated solutions for the given problems.
