How do elevators work?
When you step into an elevator and close the door, you had passed through two doors and are now standing in a box (or the elevator car) inside a vertical passageway (called the lift shaft). One door is in the walls of the floor that you got off, and the other door is part of the car itself.Inside the shaft are hoisting cables attached to the top of the car. The cables run over a sheave (pulley) connected to an electric motor at the top of the shaft. The other end of the cables is connected to a heavy steel weight called a counterweight. When the car goes up, the counterweight goes down; when the car goes down, the counterweight goes up.How the counterweight reduces to a minimum the power needed to operate the elevator ...Weight of counterweight = Weight of the car + (about) ½ of its maximum passenger loadSo when the elevator operates, it needs power only to lift the weight of the extra passengers in the car; the rest of the weight is balanced by the counterweight.
What material is in elevator counter weight?
A typical material is cast iron plates or blocks made for this purpose.
How do you Calculate elevator counterweight weight?
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.
Why is it important to design an aircraft so that its weight is distributed evenly?
It's very important when you design the plane that the plane weight is distributed evenly. The plane need it's gravity center in the center of the fuselage (On it's wings). For example: Air Midwest Flight 5481 took-off with the more weight in the tail than in the nose, the plane entered in stall 5 seconds after take-off and crashed in a hangar killing all 19 passengers and 2 crew.
An elevator has a mass of 600 kg not including passengers The elevator is designed to ascend at constant speed a vertical distance of 24 m in 15 s It is driven by a motor that can provide up to 30?
power = 40hp =29828w P=work done divided by time =>P=dW/dt=F.v where f is the force and v is the velocity v=d/t=20/16=1.25m/s =>F=P/v=29828/1.25=23862.4 N This F is the force applied by the elevator to carry itself and the passengers These forces are: Weight of the elevator Wele=600*9.81=5886N Weight of the passengers Wpas=9.81m => F-Wele-Wpas=ma for this elevator to hold the maximum number of passengers it means that the force applied by the weight of the elevator plus that of the passengers must be equal to the force provided by the motor thus rendering the elevator at rest => acceleration (a)=0 =>F-Wele-Wpas=0 =>23862.4-5886-9.81m=0 =>9.81m=17976.4 =>m=1832.5kg If the average mass of a passenger is 65 =>maximum number of passengers that can ride in the elevator are 1832.5/65=28.2 => approximately 28 passengers can ride in the elevator
What are the official physics terms for time mass area length weight and volume?
time . . . . seconds mass. . . . kilograms area . . . . square meters length . . . meters weight . . . newtons volume . . . cubic meters or liters
Elevator counter weight?
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.
An example where the measurement of tensile strength is important to the use of a material in industry?
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.
What is the weight in newtons of a 5kg mass?
That depends on the amount of gravity, of course. Weight = mass x gravity. Near the Earth's surface, the value for gravity is approximately 9.8 (meters per square seconds).That depends on the amount of gravity, of course. Weight = mass x gravity.

You are standing on a scale in an elevator Suddenly you notice your weight decreases What do you conclude?
The elevator is accelerating downwards.
How does the tires of the vehicles take the weight of many passengers?
The tyres of the vehicles does take the weight of all the vehicle, so they does take the weight of passengers as well.
What is the maximum distance that a 60-watt motor may vertically lift a 90-newton weight in 7.5 seconds?
5.0 meters
What is the speed of a 35 lb weight moving 8 meters in 5 seconds?
If you divide the distance by the time, you get the average speed during that time. The weight doesn't affect the calculation.
When going up in an elevator your weight reported by a scale increases?
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 I am in an elevator that is traveling upward at constant speed How does weight compare to your normal weight on the ground?
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.
What is the maximum weight on a dover elevator?
1200 pounds
