How many pounds of force must a man exert on one end of a 10 ft lever to lift a 200 lb rock on the other end if the fulcrum is 2 ft from the rock?

to balance moment
10 feet x force = 2 feet x 200
force = 40 pounds

What does fulcrum mean in math?
Fulcrum is the point that a lever rests or is supported.
What does a lever look like?
A lever is like a pole with a fulcrum. Here is a picture: ---------------------- ^ the triangle, which is supposed to be the fulcrum, is supposed to be attached to the k=line, which is the lever. Hope I helped! --Contributor ; )
Is a lever an inclined plane?
No. An inclined plane is simply a two-dimensional surface with a slope to it in the third dimension. A lever is a three-dimensional object which also requires a fulcrum (or leverage point) to act as a force transmitter, amplifier or attenuator.
A bar that is free to pivot about a fixed point is a?
Fulcrum * * * * * The fulcrum is the fixed point. The bar is a lever. Admitedly, it would help if questions were asked properly.
What bar that turns around a fixed point called fulcrum?
That's known as a lever.
What is The force that you exert on a lever called?
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
What is the term for the point on which a lever points?
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
What is the point about which a lever pivots or rotates?
The point about which a lever pivots or rotates is called the fulcrum. It acts as the fixed point from which the lever can move and exert force on an object. The position of the fulcrum determines the mechanical advantage of the lever system.
What is the point called on which a lever rests?
The point on which a lever rests is called the fulcrum. It acts as a pivot point around which the lever rotates to exert a force.
What is a lever's effort arm?
It is the part of a lever, where external force is applied in order to do work.
What the point of rotation in the lever system?
The point of rotation in a lever system, known as the fulcrum, serves as the pivot point around which the lever can move. It enables the lever to exert a mechanical advantage by allowing the input force to be converted into an output force on the load. The distance between the applied force and the fulcrum determines the leverage and magnification of force.
The fix point of a lever is called a?
The fixed point of a lever is called a fulcrum. It is the point around which the lever rotates when a force is applied.
What is a support called on a lever?
inclined plane
Levers explain how the force applied by a lever is affected by its distance from the fulcrum?
In a lever, the force applied is inversely proportional to the distance from the fulcrum. This means that the farther away the force is applied from the fulcrum, the less force is needed to lift the load. This relationship is governed by the principle of torque, where force is multiplied by distance.
Point around which a lever rotates?
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
What is the lever which the effort force is between the resistance force and fulcrum?
This is a second-class lever. The resistance force is located between the effort force and the fulcrum in this type of lever. An example of a second-class lever is a wheelbarrow.
What is the machanical advantage we gain by using a lever?
The mechanical advantage gained by using a lever is determined by the ratio of the distance from the fulcrum to the point where the input force is applied compared to the distance from the fulcrum to the point where the output force is applied. This ratio helps multiply the input force to exert a greater output force, making it easier to lift or move heavy objects using a lever.
