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.
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.

Lift, thrust, drag, and gravity affects all flying objects and wildlife. The blades of the helicopter provide lift, drag and thrust.
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.
drag you pull across the ground lift you pick up and take around
Lift, weight, thrust and drag.
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.
