Question

a wheelbarrow has an output distance that measures 0.33 m from the loads center of mass to the wheel. the input distance measures 1.0 m from the handles to the wheel. what is the mechanical advantage of the wheelbarrow? do not include units in your answer.

Explanation:

Step1: Recall mechanical - advantage formula

The formula for the mechanical advantage (MA) of a simple machine like a wheel - barrow is $MA=\frac{\text{input distance}}{\text{output distance}}$.

Step2: Identify input and output distances

The input distance $d_{i}=1.0$ m and the output distance $d_{o}=0.33$ m.

Step3: Calculate mechanical advantage

$MA = \frac{d_{i}}{d_{o}}=\frac{1.0}{0.33}\approx3.03$.

Answer:

3.03
