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.
A typical material is cast iron plates or blocks made for this purpose.
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.
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.
The maximum weight limit of the elevator is 2000 pounds. Exceeding this limit could pose a safety risk and may cause the elevator to malfunction. It is important to adhere to weight restrictions for the safety of all passengers.
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
Yes, an elevator can be considered a first class lever system because the fulcrum (pivot point) is located between the effort (force applied to move the elevator car) and the load (weight of the elevator car and passengers). By adjusting the balance between the effort and the load, the elevator can move up or down effectively.
Sensors in lifts are used to detect the presence of passengers and provide information to the lift control system. They can help prevent elevator doors from closing on passengers, ensure that the lift car is at the correct level for boarding, and monitor weight limits to prevent overloading. Overall, sensors improve the safety, efficiency, and performance of elevator systems.
An elevator counterweight is a weight that is used to balance the weight of the elevator car. It is connected to the elevator car by a cable, which wraps around a pulley system. The counterweight moves in the opposite direction of the elevator car, helping to reduce the amount of energy needed to lift and lower the car.
Yes, your weight appears to decrease slightly when an elevator goes down. This is because you and the elevator experience a decrease in acceleration as the elevator descends, which temporarily reduces the force acting on your body and hence, your perceived weight.
If my weight decreases while standing on the scale in an elevator, it likely means that the elevator is accelerating downward. This decrease in weight is due to the elevator and myself accelerating at the same rate, creating a sensation of weightlessness.
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.
If your weight increases while riding in an elevator, you are likely going upwards. As the elevator moves upwards, you experience a sensation of increased weight due to the acceleration.
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.

Your weight increases when going up in an elevator due to the sensation of increased force acting on your body as the elevator accelerates upwards. This is known as apparent weight, which is influenced by both the gravitational force and the acceleration of the elevator.
Time, mass, area, length, weight, and volume are official physics terms that are commonly used in the field of physics and science. These terms are fundamental quantities used to describe the physical properties of objects and events. Time is measured in seconds (s), mass in kilograms (kg), area in square meters (m^2), length in meters (m), weight in newtons (N), and volume in cubic meters (m^3).
