The crane lifts in 20 seconds vertically up to a height of 10 meters a load weighing 5000

The crane lifts in 20 seconds vertically up to a height of 10 meters a load weighing 5000 Newtons what mechanical power does it develop during this rise

Initial data: t (lifting time) = 20 s; h (lifting height) = 10 m; P (weight of the load lifted by the crane) = 5000 N.

The mechanical power that the crane could develop can be determined by the formula: N = A / t = F * S / t = P * h / t.

Let’s make the calculation: N = 5000 * 10/20 = 2500 W (2.5 kW).

Answer: The crane has developed a mechanical power of 2.5 kW.
