A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the mechanical advantage of the lever?

Asked by Nila210

Answer (2)

The mechanical advantage is (4meters) / (0.8meter) = 5 .

Answered by AL2006 | 2024-06-24

The mechanical advantage (MA) of the lever is 5, which indicates that it multiplies the effort force by five times. This allows for easier lifting of heavy objects. The formula used is MA = Input Arm / Output Arm.
