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 25% b 4% C 25% d 400%
To find the percentage efficiency, we need to divide the actual mechanical advantage (AMC) by the theoretical mechanical advantage (TMC) and then multiply the result by 100.
% Efficiency = (AMC / TMC) * 100
Given that AMC = 10 J and TMC = 40 J, we can substitute these values into the equation:
% Efficiency = (10 / 40) * 100
Simplifying:
% Efficiency = 0.25 * 100
% Efficiency = 25%
Therefore, the correct answer is option C: 25%.
