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 MA of the lever?

Respuesta :

Lanuel

Answer:

Mechanical advantage = 5

Explanation:

Given the following data;

Length of input arm = 4 meters.

Length of output arm = 0.8 meters.

To find the mechanical advantage;

[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]

Substituting into the formula, we have;

[tex] Mechanical \; advantage = \frac {4}{0.8} [/tex]

Mechanical advantage = 5
