The golden rule does not refer to the fulcrum formula. The Golden Trinity refers to three aspects of the problem, including its origin, present situation and development trend. This concept is often used in the process of problem analysis and solution, which helps to fully understand and solve problems. The fulcrum formula is a mathematical formula, which is used to calculate the reaction force of the stressed point on the fulcrum, and is mainly used in physics, mechanics and other fields. The two are different concepts, and there is no direct connection.
