If your actual mechanical advantage is 10 J and the theoretical is 40 J, what is your percent efficiency? Hint: % Efficiency = (Actual MA/Ideal MA) * 100(1 point) Responses 0.25% 0.25% 25% 25% 4% 4% 400%

1 answer

To find the percent efficiency using the provided formula:

\[ \text{Percent Efficiency} = \left(\frac{\text{Actual MA}}{\text{Ideal MA}}\right) \times 100 \]

Substituting the values:

  • Actual MA = 10 J
  • Ideal MA = 40 J

We have:

\[ \text{Percent Efficiency} = \left(\frac{10}{40}\right) \times 100 \]

Calculating that:

\[ \text{Percent Efficiency} = \left(0.25\right) \times 100 = 25% \]

Thus, the correct response is 25%.
