WebMar 8, 2024 · Step 1: Determine the inclinations of all inclined members. In this case tan θ = 3/3 = 1. ∴ θ = 45°. Step 2: Look for a joint at which there are only two unknowns. If such a joint is not available, determine the reactions at the supports, and then at the supports, these unknowns may reduce to only two.
