The rope pulling force when lifting the elevator is equal to 40,000 N. What work does the engine

The rope pulling force when lifting the elevator is equal to 40,000 N. What work does the engine do when lifting the elevator to a height of 25m.

To calculate the work done by the motor used when lifting the elevator, we apply the formula: A = F * S = T * h.

Values of variables: T – rope tension force (T = 40,000 N = 40 * 10 ^ 3 N); h – lift height (h = 25 m).

Let’s make a calculation: A = T * h = 40 * 10 ^ 3 * 25 = 1 * 10 ^ 6 J = 1 MJ.

Answer: The motor used when lifting the elevator should have done a work of 1 MJ.
