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%.
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
