What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
What fluid opposes lift?
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
Why does the input force have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
What is the role of lift in flight?
"Lift" is the force that acts opposite to gravity. If 'lift' can be made to exceed the weight of the craft, then the net vertical force on it is directed upward, and the craft can rise.
How much work can a person do to lift a 200-N weight 1.5m above his head?
Work = Force * Distance Force = 200N (gravity already taken into account because of N) Distance =1.5m Work = 200N * 1.5m Work = 300N*m = 300 Joules
A lever is used to lift a load weighing 200N The force needed was 600N What is the mechanical advantage of this first class lever?
3 x 200 N = 600 N.
How much down force is needed to lift a helicopter?
The same force as the weight of the helicopter and its crew and cargo.
A fixed single pulley that is used to lift a block does what?
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
How many pounds of force does it take to lift a 100 pound man out of corn up to his waist?
If you have a man submerged up to his neck in corn and you want to know how many pounds of force it will take to lift him out, information about the volume, weight, mass, density would be needed in order to calculate the force needed.
What minimum downward force needed to lift the 120 Newtons weight?
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
What fluid opposes lift?
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
How much force to apply to a piston with an area of 10 cm2 to lift an object weighing 200n on a piston with an area of 50 cm2?
400 N 400 N / 10cm2 = 2000 N / 50cm2
How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
