To find the efficiency of the stationary unit used, we apply the formula: η = m * g / Fп.
Values of variables and constants: m – weight of the cargo (m = 50 kg); g – acceleration due to gravity (g ≈ 10 m / s2); Fп – applied force (Fп = 600 N).
Calculation: η = m * g / Fп = 50 * 10/600 = 0.833 = 83.3%.
Answer: The fixed block used has an efficiency of 83.3%.
