Best Answer

Simply because the cables that hold the elevator cannot resist to a certain weight. There is a weight limit to insure that the cables don't break. The weight limit might also be determined by the lifting power of the mechanism driving the elevator. This is probably a bigger concern than the cables; normally engineers build in a pretty hefty safety factor on those (and some elevators don't use cables at all but are powered by a hydraulic system).

What is formulae for elevator's counter weight calculation?

The mass must be greater than the mass of the elevator including the maximum amount of cabling that it has, plus the carrying capacity plus a safety margin.


How do you draw an elevator free body diagram?

Draw an arrow pointing upwards for the tension force and an arrow pointing downwards for the weight of the elevator which will be its mass times gravity (mg). Also, draw another arrow pointing downwards for any mass that may be inside the elevator (another mass times gravity arrow but for a separate weight) and add that value to that of the weight of the elevator. Depending on the direction that the elevator is moving (up or down) draw another arrow respectively and label it "a" for acceleration.


Is weight changeable property compared to mass?

Yes. Ride an elevator and your weight changes, but your mass remains constant.

What is the acceleration of an elevator if a student stands on bathroom scale in the elevator and the scales reads 836 newtons and the elevator is moving upward?

We have no way to calculate that, unless you also tell us either his mass, or else his weight on motionless ground, like when the scale is on the bathroom floor.


What force is needed to accelerate an elevator with a mass of 1000 kg upward at a rate of 2 m per second squared?

Weight of the elevator = 1000kg x -9.8m/s2 = -9800N Upward force acting on the elevator = 1000kg x 2m/s2 = 2000N Net force = upward force - weight of elevator = 2000N - (-9800N) = 11800N
