Is an Elevator a Speed or a Force Multiplier

Question

Is a elevator (that is set up on a system like this)

http://www.all-science-fair-projects.com/science_fair_projects/57/696/245147ccd278284f21ff76f593804398.html

a speed or a force multiplier. Why?

Thanks for your help!!

Answer 1

The elevators principally works like that.But in normal conditions like 5 stok buildins you have got 1 main spindle 1 centring spindle a motor, a gear , counter weight, cabin,special steel ropes, rails and doors,stage displays,buttons, control cabinet and safety devices ( speed governer, brakes ),travelling cable

To decrese the motor power there are some optimal solutions.When you share the wight ( forces ) you need smallar motors and gears.When you have a problem with the machine room locations you have to find some solutions.Normally the machine rooms are at the top of the building , but in some cases they can be at the bottom and at the side of the shaft.They can be also electromechanical and hydraulic.with this explination I hope that you understood.

The system works with balancing system, with friction.Elevator is not a force multiplier vice versa a force or load sharer.About the speed it is up to the design, but every overdesign is money or every comfort has a price.The spped starts with 0,63 mt/ sec up to 5 mt /sec ( there are faster elevators depending of the height of the building.)

Answer 2

for me, it is a force multiplier..

because it can lift a heavy weight easily but slowly..
