a) How would you use a cuboid to show that the effect of force depends on area of contact?

Answer 1

Answer:

by hand and by pen and stationary

Answer 2

I would use a cuboid to show that the effect of force depends on the area of contact by applying force on its face, edge and vertex.

- First, let us put some force on the face of the cuboid by our thumb.

- Here, the area of contact is the area of our thumb and we will not feel any pressure.

- Now, put the same force on the edge of the cuboid.

- This time, we can feel the sharp edge of the cuboid on our thumb due to less area in contact.

- If we put the same force on the vertex of the cuboid, then it will pierce into our thumb as the area of contact is the minimum.
