A lever is balanced when the product of the effort force and its distance from the fulcrum is equal to the product of the load force and its distance from the fulcrum. If the effort force is 300 N and the load force is 1200 N, and the effort is applied 2 m from the fulcrum, calculate the distance from the fulcrum to the load.

答案：Let the distance from the fulcrum to the load be \( x \). According to the principle of levers, \( 300 N \times 2 m = 1200 N \times x \). Solving for \( x \) gives \( x = \frac{300 N \times 2 m}{1200 N} = 0.5 m \).
