Dear former creators of this web-site,
I believe that you should have the answer to questions kids ask you because then, how would kids get answers to their curious questions? It isn`t a really good idea for them to answer because they would want to learn. They might not know the answer.I believe this and just want you to take notice of it.
Sincerely,
A concerned teacher
P.S. Please give the answers to children`s curious questions.
Thank you
fulcrum
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.
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 fulcrum(pivot) is the screw in the door.
A Fulcrum is a simple machine invented by the greek mathematician Archimedes who theorized that with a large enough fulcrum one could move the Earth. As for use in a sentance? Here ya go. Archimedes used a fulcrum to lift the earth.
A symmetrical balance has its fulcrum at the midpoint of the horizontal bar and equal weights at either end. In an asymetrical balance the fulcrum is not at the centre and consequently the weights on the two sides are in inverse proportion to the lengths of the horizontal bar to the fulcrum.
The pivot point of a lever is called the fulcrum.
The fulcrum on a triple beam balance is located at the center of the balance where the beams pivot. This allows for precise measurement of mass by moving the riders along the beams to achieve balance.
It is the balance point of a lever. That is all there is to it!
fulcrum
The fixed balance point on a lever is called the fulcrum. It is the point at which the lever pivots or rotates when a force is applied to either side of the lever. The position of the fulcrum determines how the lever amplifies or redirects the force applied to it.
The fulcrum should be placed closer to the heavy load to balance it. By positioning the fulcrum nearer to the heavy load, more leverage can be generated to lift the load with less effort.
A seesaw in a playground is an example of a fulcrum. The board that the children sit on acts as the lever, while the point where the seesaw pivots is the fulcrum. The position of the fulcrum determines the balance and movement of the seesaw.
because it balance the lever
move the plank closer to the fulcrum to be able to lift the rock off the ground
Position the fulcrum so that the distance from the fulcrum to the one pound ball is twice the distance from the fulcrum to the two pound ball.
If it is a level which is balanced, then it is the fulcrum. Otherwise, it is the centre of gravity.
