With the help of a simple mechanism, a useful work of 55 kJ was performed, what is its total efficiency, if the total work was 89 kJ.
Initial data: Ap (useful work done with a simple mechanism) = 55 kJ (55 * 10 ^ 3 J); Az (full work) = 89 kJ (89 * 10 ^ 3 J).
The total efficiency of a simple mechanism is calculated by the formula: η = Ap / Az.
Calculation: η = 55 * 10 ^ 3 / (89 * 10 ^ 3) = 0.618 (61.8%).
Answer: The total efficiency of a simple mechanism is 61.8%.
