The Australian lift:
Is a type of shoulder lift used to move a patient who is unable to assume a sitting position on a bed or other surface. The lift is executed by two persons, one on each side of the patient, who place their shoulders near the patient under the patient's axillae. At the same time, the two lifters grasp each other's hands under the patient's thighs and make coordinated movements needed to lift the patient onto or from a bed or wheelchair.
A Drag lift:
Is when the carer/person pulls a patient up by pulling/dragging them under their arms. Its very painful for the patient and is classed as abuse these days. It can tear and bruise skin. If a person can't get up on their own, then a hoist should be used.
coefficient of drag in 0 lift
lift decrease and increase drag
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
A higher angle of attack has an increase of both lift and drag.
The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.
drag you pull across the ground lift you pick up and take around
Lift, weight, thrust and drag.
As lift increases for helicopters, the angle of attack of the rotor blades must also increase to generate more lift. This higher angle creates more drag due to increased air resistance and turbulence. Additionally, the higher lift forces can lead to increased induced drag, which is generated as a byproduct of producing lift.
Lift is equal to drag, so if the drag was 12000N (newtons) the lift would be 12000N. it is mainly used for slowing the aircraft down for decend.
drag
NO!
Induced drag is caused by the creation of lift on an aircraft's wings. As the aircraft generates lift, it creates vortices at the wingtips, which result in a rearward force component known as induced drag. This drag increases as the angle of attack or lift produced by the wings increases.
