What force is created when an object moves through a fluid like aircraft moves through air?
Either drag (air resistance) slows the aircraft down, or lift (Bernoulli's principle) raises it up. When more air goes under the wing than over it, the aircraft "wants" to move up because objects favor movement into low pressure zones.
How does a lift work?
The pulley in the mechanical device work together to make the lift move up and down. Counter weights.
How much down force is needed to lift a helicopter?
The same force as the weight of the helicopter and its crew and cargo.
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 is the difference between elevator lift and crane lift?
The way they lift the load.

What are the two parts of a lift that goes down a mine called?
The two parts of a lift that goes down a mine are the cage, which carries miners and equipment, and the hoist system, which controls the movement of the cage up and down the shaft.
What do you call the two parts of the lift that goes down on a mine?
The two parts of the lift that goes down in a mine are commonly referred to as the "cage" and the "counterweight." The cage carries workers and equipment to and from the mine, while the counterweight helps balance the load, making the lift operation more efficient and safer. Together, they facilitate the vertical transport necessary for mining operations.
What do you call the two parts of the lift that goes down to a mine?
The two parts of a lift that goes down to a mine are typically referred to as the "cage" and the "skip." The cage is the compartment in which miners and materials are transported, while the skip is the container used specifically for transporting ore or other excavated materials. These terms may vary slightly depending on regional mining practices and terminology.
What do we call two parts of the lift that goes down a mine?
The two parts of a lift that goes down a mine are typically called the "cage" and the "skip." The cage is used for transporting personnel and materials, while the skip is designed specifically for hauling ore or rock. Both are essential for efficient mining operations, allowing for the vertical movement of resources and workers between the surface and underground levels.

What do you call the two parts of a lift that go down a mine called?
The two parts of a lift that go down a mine are called the "cage" and the "counterweight." The cage is the compartment that carries personnel and materials down into the mine, while the counterweight helps balance the cage to ensure smooth and efficient operation of the lift system.
What are the two parts of lift that go down in the mine called?
The two parts of a lift that go down in a mine are called cages. These cages are used to transport miners and equipment up and down the shaft.
What are the 2 parts of lift that go down a mine called?
The two parts of a lift that go down a mine are called the cage, which is the compartment in which miners and materials are transported, and the counterweight, which provides balance and stability to the lift system.
What goes up and down a narrow shaft and rarely leaves?
A lift
