A typical material is cast iron plates or blocks made for this purpose.
12,000 N, since force is equal to weight in this situation
An elevator has a weight limit of 350 pounds a box of machine parts weighs 25 pounds which inequality best describes the maximum number of boxes b that the elevator can hold
Elevator Counterweight = Half of Elevator Maximum Capacity + Cab Weight For eg: 10passenger Elevator = 10*80 = 800Kgs Counter Weight is 800/2 = 400Kgs + Cab Weight This is just to create a imbalance between Elevator cab and counterweight in order to save power in the drive.
get in an elevator
To calculate the counter weight just simply use this formula V3x (-)> 3.16 + belt radius = weight it took me 14 days to come up with this theory use it wisely Please and thank you.
The suitable weight for an elevator counterweight is equal to the weight of the elevator itself. This ensures that the elevator moves smoothly and safely without any jerking or swaying. ESCON Elevators use high-quality counterweights that are perfectly balanced, ensuring a smooth and comfortable ride for every passenger.
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.
To counteract the weight of the barricades arm. This way the counter weight will do most of the work when the barricade is lifted.
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.

Of the maximum weight capacity of an elevator in a skyscraper (tensile strength of the elevator cable). you don't want it to snap when people are on it and send them hurtling hundreds of meters downwards.
The elevator is accelerating downwards.
Not really. It is not the fact of GOING UP that makes your apparent weight increase, but the fact that it is ACCELERATING UPWARD. For example, while the elevator goes up at a constant speed, your apparent weight will be the same as if it weren't moving.
If the elevator's speed is constant (acceleration is zero), regardless of whether it's up or down,then your weight in it is the same as your normal weight on the ground.It should be easy to carry a bathroom scale onto an elevator with you some day and check it out.
The counter-weight serves to balance the crane when it's lifting anything. If there was no counter-weight, the crane would topple over !
