These tasks: Ap (useful work done when using the taken lever) = 100 J; Apolle (full work of the lever) = 120 J.
To determine the efficiency of the taken lever, we will use the formula: η = Ap / Apoln.
Let’s make a calculation: η = 100/120 = 0.833 or 83.3%.
Answer: The efficiency of the taken lever is 83.3%.
