A lever pivots on a fulcrum.
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
That is the Fulcrum.
a lever with an effort arm of 2 inches
By using the principle of the lever.
No, the principle behind scissors is the "lever" and "shear".
According to Archimedes, the principles of the lever include the Law of the Lever and the Principle of Virtual Work. The Law of the Lever states that the product of the weight being lifted and its distance from the fulcrum is equal to the product of the weight applied to the other end and its distance from the fulcrum. The Principle of Virtual Work states that if a lever is balanced and one side is moved along a circular arc, the distances of the weight and the weight applied to the other end from the fulcrum are inversely proportional to their magnitudes.

Boyles law certainly applies, and to some degree, so does the principle of a lever.
a salad spinner uses gears to speed up turning motion. Gears are based on the lever principle. So in essence, yes it is a leaver.
A lever works on the principle of using torque. A screw driver is used as a lever because the relatively broader handle produces much more torque for the same force as compared to the narrower blade of the screw driver.
Yes. That's called a lever.
Is this for THE MEDITERRANEAN WORLD OF GREECE----II? I have the same worksheet lol. The answer is Archimedes
A screw multiplies effort through the principle of the lever. The screw part of the fastener is actually a small lever that allows the screw to bite and dig into other materials.
