The excavator lifts the bucket to a height of 2.5 m in 10 seconds. Bucket weight with soil 2000 kg. Determine the engine power generated when lifting a loaded bucket
Initial data: h (excavator bucket lifting height) = 2.5 m; t (bucket lifting duration) = 10 s; m (excavator bucket weight with soil) = 2000 kg.
Constants: g (acceleration due to gravity) ≈ 10 m / s2.
The power of the excavator engine when lifting a loaded bucket can be calculated by the formula: N = A / t = Ep / t = m * g * h / t.
Calculation: N = 2000 * 10 * 2.5 / 10 = 5000 W (5 kW).
Answer: The power of the excavator engine when lifting a loaded bucket is 5 kW.
