Can you achieve 100 percent efficency with a lever and fulcrum?

Not if you consider the energy expended to grip or engage the lever--this does account for a minimum amount of lost efficiency

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 ; )
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 are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
Why is the fulcrum in a lever important?
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
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
A lever pivots on its?
A lever pivots on its fulcrum, which is the fixed point where the lever rotates. The position of the fulcrum affects the mechanical advantage and function of the lever.
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 part of a lever which stays on a fixed part?
The part of a lever that stays on a fixed part is called the fulcrum. The fulcrum is the point around which the lever rotates or pivots when a force is applied on one end of the lever. It acts as a pivot point for the lever to achieve mechanical advantage in moving an object.
What are parts are of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
What are the parts a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
Does a lever pivot on a fulcrum or an axle?
fulcrum
What determines the class of a lever?
The class of a lever is determined by the relative positions of the fulcrum, load, and effort. In a first-class lever, the fulcrum is between the load and effort; in a second-class lever, the load is between the fulcrum and effort; in a third-class lever, the effort is between the fulcrum and load.
What is the balance point called on a lever?
The balance point on a lever is called the fulcrum. This point is where the lever pivots or rotates to allow for a mechanical advantage when lifting or moving objects.
What is the difference between a lever and a fulcrum?
A lever is a rigid bar that rotates around a fixed point called a fulcrum. The fulcrum is the point on which the lever pivots or rests. In simple terms, the lever is the tool used to lift or move objects, while the fulcrum is the support point that enables the lever to work.
