Question

The blade of a metal cutter is shorter than that of the scissors used by tailors. give reason​

Answer 1

Answer:

Yes.

Explanation:

In metal cutter the effort distance is greater. Metals are very hard. In order to cut the metals we need more energy and effort. If the effort distance is greater than load distance there will be magnification of force and the metals could easily cut. So the blade of metal cutter shorter than that of scissors used by the tailors.

Answer 2

Explanation:

Metals are very hard substances. In order to cut the metal, we need more force pressure efforts and energy. Therefore, if the effort distance is greater than the low distance, there will be a magnification of force and the metal could cut easily. And if the force is less than the low distance, there will be no magnification of force and the matter could not be cut easily. In metal cutter sheer, we need a larger mechanical advantage to overcome the resistive load while cutting the metal sheet. Thats why the blade of a metal cutter shorter than the scissor used by it.
