how is a pair of scissors similar to a traditional see sow
Answers
Explanation:
Both are based on a lever using a pivot point. The seesaw with 2 people on opposite sides, the people being of different weights, can be equalized by moving the heavier person toward the pivot so that a balance point can be achieved. This shows that the longer side with less force can offset much greater force by placing the greater force needed closer to the pivot. Scissors work the same way, especially different type of snips used for tough but malleable material. Or like wire cutters where the nose is very stubby but the handles are longer. You hands created a higher force the closer to the opposite side of the pivot you get the material. The major difference is having two blades on the scissors as opposed to a single piece on a seesaw. But the principle of the lever force versus the load force remains the same. Mathematically this is described by this formula: Fede=Fldl. F is the force applied, d is the length to the fulcrum, the sub-e denotes load effort, sub-l equals needed length. Since the two must be equal, then the length to the pivot is a prime factor. The scissors and seesaw both work on this principle.
