1. **Stating the problem:** We have a jointed wedge system and need to find the forces and tension by taking moments. 2. **Formula and rules:** The moment (torque) about a point is given by $$M = F \times d$$ where $F$ is the force and $d$ is the perpendicular distance from the point to the line of action of the force. 3. **Step 1: Identify the pivot point** where moments will be taken to eliminate unknown forces acting through that point. 4. **Step 2: Write the moment equilibrium equation:** Sum of clockwise moments = Sum of counterclockwise moments. 5. **Step 3: Express forces and distances:** Let tension be $T$, force on wedge be $F$, distances from pivot be $d_1$, $d_2$ respectively. 6. **Step 4: Set up the equation:** $$T \times d_1 = F \times d_2$$ 7. **Step 5: Solve for unknown force or tension:** $$T = \frac{F \times d_2}{d_1}$$ 8. **Step 6: Check other equilibrium conditions:** Sum of vertical forces = 0, sum of horizontal forces = 0 to find all unknowns. This method allows you to find the tension and forces in the jointed wedge by taking moments and applying equilibrium rules.
