What type of stress is caused by two plates pushing into one another?

shear

force

compression

tension

Answer 1

It's very easy to answer. You need to use ur hands for understanding choices B, C and D. Then we can concentrate on Choice A.
Ready?

Answer 2

ok

Answer 3

imagine each of your hands as a plate.
Choice D: Do your hands pull each other?

Answer 4

no

Answer 5

Push your hands to each other and answer my question above.

Answer 6

no they do not

Answer 7

Ok, So D is incorrect.

Think of compression. Do they compress each other?

Answer 8

yes kinda

Answer 9

Kinda, but what if they were IRON HANDS? :)

Answer 10

then no

Answer 11

Good.
So Choice C is incorrect.

Do you know what is the shear stress? For example when you cut an apple to halves it's the shear stress what you make. Do you think your hands make shear stress when you push them to each other?

Answer 12

yes

Answer 13

Do your hands cut each other ? !!!!!!!!!! :)

Answer 14

noo!

Answer 15

sure no. It's not shear stress then. Choice A is incorrect. So what would be the correct choice?

Answer 16

b

Answer 17

Yes. Seems to be the Choice B.
But let me give you some more explanations:
1) We don't have Force Stress. I guess Choice B should be replaced by Normal stress.
2) If you know the plates are Compressible then Choice B is NOT the correct choice. What would be the correct choice then?

Answer 18

2

Answer 19

If it's compressible then it can be compressed and you should choose the Choice C.

Answer 20

ok

Answer 21

thanks

Answer 22

I will give you a metal them I will close the question

Answer 23

In one side, as we do not have anything like FORCE STRESS, we should not choose it. In the other side we know CLEARLY that our hands do not cut each other (Tension) or Pull (Tension) each other. Choices A and D are incorrect for sure.

Here we better assume that disks are compressible and choose the choice C.
You got it?
