Σ F, = 0 Because each joint is subjected to a coplanar and concurrent force system, no moment equations are needed. The analysis of a truss should always begin with a joint that has at least one known force and at most two unknown forces. These equations of equilibrium yield two algebraic equations that can be solved for at most two unknowns.

Question
### Analyzing Truss Equilibrium **Equilibrium Equations:** \[ \sum F_y = 0 \] Because each joint is subjected to a coplanar and concurrent force system, moment equations are not needed. The analysis of a truss should always begin with a joint that has at least one known force and at most two unknown forces. These equations of equilibrium yield two algebraic equations that can be solved for at most two unknowns. --- #### Part A: As shown, a truss is loaded with forces \( P_1 = 193 \text{ lb} \) and \( P_2 = 391 \text{ lb} \) and has the dimension \( a = 3.80 \text{ ft} \). **Diagram Explanation:** The truss is in the shape of a right triangle with beams connecting points A, B, C, and D. At point A, the truss is attached to a wall, and at point C, it rests on a support. The forces \( P_1 \) and \( P_2 \) act downward at points D and B respectively. The dimensions between the joints are defined by \( a \). **Task:** Determine \( A_x \) and \( A_y \), the magnitudes of joint A's reaction forces in the x and y directions, respectively, and \( C_y \), the reaction force's magnitude at joint C in the y direction. --- For further exploration and practice, students are encouraged to solve the equilibrium equations and analyze the forces acting on this truss.
