To find the magnitude of the force acting on the triangle, we can use the relationship between moments and forces. Since and are points where the moments are equal and the moment at is negative, we can calculate as follows:
  1. First, determine the lengths of the sides using the Pythagorean theorem. Since the triangle is right-angled at :
  2. Moments about point give:
  3. Moments about point give:
  4. Since the moments at point are negative, we consider the opposite direction for the calculation:
Thus, we conclude these calculations point to an average force that must satisfy all conditions. Since and yield different answers, it is common to resolve discrepancies through vector addition if needed.
Ultimately, can be reasonably taken as the average magnitude of the forces calculated to ensure equilibrium, leading to:
