The crane lifts the load evenly to a height of 10 m in 20 seconds. what power does the crane develop if the load is acted upon by a gravity force of 5000N.

Initial data: h (height to which the crane lifted the load) = 10 m; t (duration of lifting the load) = 20 s; Ft (the force of gravity that acts on the lifted load) = 5000 N.

The power developed by the crane when lifting the load is determined by the formula: N = A / t = Ft * h / t,

Let’s calculate: N = 5000 * 10/20 = 2500 W or 2.5 kW.

Answer: When lifting a load, the crane will be able to develop a power of 2.5 kW.
