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

To calculate the percent efficiency, we first need to find the actual mechanical advantage (MA) and the ideal mechanical advantage (MA).

Given:
Actual mechanical advantage (MA) = 10 J
Theoretical mechanical advantage (MA) = 40 J

Using the formula:

% Efficiency = (Actual MA / Ideal MA) * 100

We can substitute the given values into the formula:

% Efficiency = (10 J / 40 J) * 100

Simplifying the expression:

% Efficiency = (1/4) * 100

% Efficiency = 25%

Therefore, the percent efficiency is 25%.
