With the help of a stationary block, a load weighing 50 kg is lifted, applying a force of 600 N. What is the efficiency of this block?

To find out the efficiency of the said fixed block, we will use the formula: η = Apol / Azat = Fp * h / (Fz * h) = Ft / Fz = m * g / Fz.

Const: q – acceleration due to gravity (q = 9.81 m / s2).

Data: m is the mass of the load being lifted (m = 50 kg); Fz – applied force (Fz = 600 N).

Calculation: η = m * g / Fz = 50 * 9.81 / 600 = 0.8175 or 81.75%.

Answer: The specified fixed block must have an efficiency of 81.75%.
