If your actual mechanical advantage is 1
O J and the theoretical is 40 J, what is your percent e
fficiency? Hint: % Efficiency = (Actual MA/ideal MA) * 100 a 0.25% b 4% C 25% d 400%
To calculate the percent efficiency, we can use the formula % Efficiency = (Actual MA / Ideal MA) * 100.
Given:
Actual MA = 1
Ideal MA = 40
% Efficiency = (1 / 40) * 100
% Efficiency = 0.025 * 100
% Efficiency = 2.5%
Therefore, the correct answer is b) 2.5%.
