Explain the following text primarily based on the surrounding page content:
A lever is used to lift an object with a weight of 60 Newtons. The effort force is 15 meters from the fulcrum, while the load force is 5 meters from the fulcrum. What is the mechanical advantage?(1 point)

Mechanical advantage (MA) for a lever = (distance from fulcrum to effort) / (distance from fulcrum to load). So

MA = 15 m / 5 m = 3.

(Equivalently, MA = load force / effort force. With MA = 3 and load = 60 N, the required effort would be 60/3 = 20 N, and torques balance: 20·15 = 60·5 = 300 N·m.)

So the correct choice is 3.
