what you do is you go into the elevator, with another person on the outside. you grabve there under wear, quickly close the elevator doors, and click the button to go tot he highest floor. keeping tight grasp on the person's underwear, wait until you are at the top floor. then let go. and get off the elevator, take the stairs don, and check out the person. the friction of you holding on to there under wear should have lifted and ket the on the top of the elevator doors. and the only way to get them down is to ride the elevator down, if the gerson's underwear has. if already ripped.
Gravity does work on the elevator when it moves up or down, but the amount of work done depends on the distance the elevator travels and the weight of the elevator and its occupants.
No work is done on a person ascending an elevator as the force is in the same direction as the displacement, resulting in zero work done by the force moving the person.
A disadvantage of an elevator is the inconvenience when it does not work. People get dependent on an elevator and find it very hard to take the stairs during a breakdown even if they are physically capable of using stairs.

Passenger elevators are big pulleys powered by a motor with 6-8 cables or more that pull the elevator cab or the counter weight letting the elevator go up or down.
A. The work done in lifting the elevator can be calculated using the formula: Work = Force × Distance. The force is equal to the weight of the elevator, which is 3500 pounds, and the distance is 30 feet. Therefore, Work = 3500 pounds × 30 feet = 105,000 foot-pounds. B. The speed of the elevator can be found by dividing the distance by the time taken. Speed = Distance / Time = 30 feet / 10 seconds = 3 feet per second.
take a bazooka and bomb it

Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
get in an elevator
buttons and the ropes and pulley system so the elevator goes up if it gets pulled by the pulley system oh and i am in elementary school and i can answer it
To install an elevator, a vertical shaft has to be constructed. The approval of the design and the carpentry and electrical work should be done by the building agency. The installation of the elevators should be done by the experienced professionals.
