Calculating the torque angle involves determining the perpendicular distance from the line of action of a force to the fulcrum. A construction line from the tension vector to the pivot can simplify trigonometric calculations. The confusion arises when subtracting angles, as seen in the discussion about the tension force and the weight forces. Understanding that torque is defined as force times perpendicular distance is crucial, and the concept of moments can help clarify calculations. The diagram provided is straightforward, and using basic trigonometry should aid in finding the necessary lengths and angles.
