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
a
0.25%
b
25%
c
400%
d
4%
The percent efficiency can be calculated using the formula:
% Efficiency = (Actual MA/Ideal MA) * 100
Substitute the given values:
% Efficiency = (10/40) * 100
% Efficiency = 0.25 * 100
% Efficiency = 25%
Therefore, the answer is option B) 25%.
