A simple machine lifts a load of $200\text{ N}$ when an effort of $50\text{ N}$ is applied to it. What is the mechanical advantage of the machine?

Answer: 4 / 4.0

The mechanical advantage of the machine is

4

Mechanical Advantage (MA) is the ratio of the force exerted by the machine (load) to the force applied to the machine (effort). Dividing

200\text{ N}

50\text{ N}

yields a dimensionless mechanical advantage of

4

Identify the given values from the problem statement

Load (

L

) =

200\text{ N}

, Effort (

E

) =

50\text{ N}

Mechanical advantage is defined as the ratio of load to effort.

Apply the formula for Mechanical Advantage (MA)

\text{MA} = \frac{\text{Load}}{\text{Effort}} = \frac{200\text{ N}}{50\text{ N}} = 4

Dividing the output force by the input force gives the force amplification factor of the machine.
