What forces are acting on a helicopter when it is still?
When a helicopter is hovering (aka "still") it has the force of gravity pushing "down" toward the Earth and the force of "lift" of the spinning rotor blade(s) pushing against the surrounding air. When the gravitational force is equal to the force of lift the helicopter hovers on the vertical axis.
Calculate lifting force?
The lifting force on an object can be calculated using the formula: Lifting Force = Weight of Object - Weight of Fluid Displaced This is based on Archimedes' principle, which states that an object fully or partially submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.
What is an example of muscular force?
Lifting a heavy object, such as a box, is an example of muscular force. The muscles in your body contract and exert force to overcome the weight of the object, allowing you to lift it.
Why is lifting a box a form of work?
Lifting a box involves exerting force to overcome gravity and move the box vertically. Work is defined as force applied over a distance, so lifting a box requires work to be done against the force of gravity as the box is raised. Thus, lifting a box involves transferring energy to the box to move it to a higher position.
Why does lifting need more force than pulling?
Lifting an object against gravity requires more force than pulling it along a horizontal surface because you are working against the force of gravity. When lifting, you are fighting against the weight of the object in addition to any other resistance present, such as friction. Pulling, on the other hand, only requires overcoming the frictional force.
What is free body diagram of a helicopter lifting off a landing pad?

When was Commando Helicopter Force created?
Commando Helicopter Force was created in 1997.
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 to built a man lifting helicopter for an engineering project?
using aeronautical principles
Do the rear blades of a helicopter lift the helicopter?
NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.
How does the helicopter get its lifting force?
the helicopter pushes forward when the pilot pushes the cyclic control forward. that rotates the blades forward . while pushing forward on the cyclic, the pilot must also pull up on the collective control. that will add pitch to the blades, thrusting the helicopter forward.
How can you get money for helicopter flight training?
Join the army or air force as a helicopter pilot.

What is a helicopter crane used for?
