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:

An Atwood machine consists of a system of two masses that counterbalance each other.In this system, the acceleration is caused by the difference between these masses, if there are no differences between them, there is no acceleration of the system.In the case of the elevator, a counterweight system would provide a balance when there were people inside the box.This is because the counterweight would have the mass equal to the mass of the empty box and this would make the entire system not have acceleration.However, when people enter the box, there would be a difference in mass and the system would have acceleration, without forcing a greater force to do so, but using engine power.

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.

All are great precautions but you can still lift lighter and different muscles in between hard workdays. this keeps other muscles not usually used in shape.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
