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.
How much force is needed to lift 78 pounds person into the air?
Any upward force greater than 78 lbs will accelerate that person vertically upwards.
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 does the number of supporting strings affect the force needed to lift the weight?
In a Pulley System, the number of "Supporting Strings" is equal to the Force multiplier of the system. That is, if there are 4 supporting strings (plus the string you pull on), and the object being raised weighs 100 pounds, then the effort you supply is only 25 pounds. The Pulley System has a force multiplier of 4 times the input.
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 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.
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 many newtons of force are needed to lift a 500 kg box?
Newton is the amount of force required to accelerate an object of mass m to meter , In this case if we try to accelerate it to one meter , you require 500 newtons to lift the box perpendicularly. Also lifting of weight depends on the angle of applied force.
What effort is required to lift a 300 kg weight?
On earth, any vertical force greater than 661.39 pounds will lift a mass of 300 kg.
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.
How many pounds of effort force does a lever have if it has an effort arm of fifteen units long and a resistance arm of 10 units and can lift a 3-pound weight?
It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.)
How much force is needed to lift 78 pounds person into the air?
Any upward force greater than 78 lbs will accelerate that person vertically upwards.
How many people are needed to lift this TV What is the weight?
This television can be lifted by one person,it weighs less than 60 pounds.
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 is the force needed to lift a 2232000kg load at constant speed?
If the object is moving at constant speed, then the net force on it is zero.In order to have zero net force in the vertical direction, the lifting force is equal tothe gravitational force.The gravitational force is the object's weight. With a mass of 2,232,000 kg,the object's weight is21,873,600 newtons (4,920,712 pounds) .A force less than that much can't lift the load. A force greater than that much accelerates itupward. Once it's rising, a force of exactly that much keeps it rising at constant speed.
