Question

a lift is designed to lift the weight of 4000 kg to the 10th floor averaging 6 meters per floor in 10 seconds? calculate the power​

Answer 1

The power of a lift can be calculated using the formula:

Power = Work / Time

where Work is the amount of work done in lifting the weight to a certain height and Time is the time taken to do the work.

Work = Force x Distance

where Force is the weight lifted and Distance is the height it is lifted to.

First, let's calculate the work done:

Force = 4000 kg (Weight lifted)

Distance = 6 m/floor x 10 floors = 60 m

Work = Force x Distance = 4000 kg x 60 m = 240000 J

Next, let's calculate the power:

Time = 10 seconds

Power = Work / Time = 240000 J / 10 s = 24000 W

So the lift has a power output of 24000 W.
