SUMMARY
The problem involves calculating the tensions in three strings (T1, T2, T3) supporting a 21 kg weight. To solve for the tensions, one must derive three equations based on the angles of T1 and T2, and the gravitational force acting on the mass (Mg). The tensions T1 and T2 must be resolved into their horizontal and vertical components, while T3 directly equals the gravitational force. This approach ensures that all forces are balanced in both the horizontal and vertical directions.
