If your actual mechanical advantage is 1

Question

O J and the theoretical is 40 J, what is your percent e
fficiency? Hint: % Efficiency = (Actual MA/ideal MA) * 100 a 25% b 4% C 25% d 400%

Answer 1

To calculate the percent efficiency, we need to divide the actual mechanical advantage by the theoretical mechanical advantage and then multiply by 100.

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

Given that the actual mechanical advantage is 1 and the theoretical mechanical advantage is 40, we have:

% Efficiency = (1 / 40) * 100 = 0.025 * 100 = 2.5%

Therefore, the correct answer is b) 4%.
