Question

Where will the strongest force be excerted by the scissor blades to cut through a piece of material? Explain your answer.

Answer 1

Answer:

Explanation:

the cutting edges nearest the handles

Answer 2

The strongest force has to be exerted at the edges of the material. This force applied is called the shearing force.

• Shearing forces are two parallel forces that always act opposite to each other.
• This force is always perpendicular to the material it acts on.
• Force is maximum when applied in the perpendicular direction.
• Initially, the maximum force has to be exerted on the edges and it will always be perpendicular to the material.
• This is the reason why the strongest force exerted by the scissors is on the edges.
