Challenge: Truss Joint Equilibrium
As you continue your journey into structural analysis, you have already explored how to model beams, analyze loads, and even break down forces in truss structures. One of the most critical checks in designing safe and efficient truss systems is ensuring that every joint is in equilibrium. This means that the sum of all forces—both horizontal and vertical—acting at a joint must be zero (within a small tolerance to account for rounding errors). If a joint is not in equilibrium, the structure could fail or behave unpredictably under load. By calculating the horizontal and vertical components of each force at a joint and verifying their sums, you can confirm whether the structure will remain stable at that point. This approach is a cornerstone of both manual and automated structural design processes.

Write a function to check if a truss joint is in equilibrium based on a list of forces. Each force is represented as a tuple containing its magnitude and angle in degrees.
- For each force, calculate its horizontal and vertical components using trigonometric functions.
- Sum all horizontal components and all vertical components.
- Determine if both sums are zero within a small tolerance.
- Return the net horizontal sum, net vertical sum, and a boolean indicating equilibrium.
