Suppose you were designing an elevator. How could you use the concept of an Atwood machine to minimize the force required to move the elevator up and down? If possible, discuss your answer with your classmates and teacher.

Using Atwood machine concept, we can state that the elevator can use a system of counterweights that balance the weight inside the box and minimize the force required to move the elevator up and down.

We can arrive at this answer because:

With that, we can say that an elevator can act as an Atwood machine.

an elevator we can use a counterweight that has the same mass as the empty box,

Explanation:

An Atwood machine consists of two masses connected by a rope through a pulley, in this case the acceleration of the system is proportional to the difference in masses, in the case of equal masses the acceleration is zero.

In the design of an elevator we can use a counterweight that has the same mass as the empty box, in that case when there are no people in the elevator, the natural acceleration is zero and there is no need to apply any force and therefore no power is needed. the motor.

When you have people inside, the power of the motor is what you need to lift the people, not the box, this reduces the power needed by the elevator motor by a high factor.

the bal will not change its velocity.
