Okay, first of all thank you for asking this question to me(A2A)

Well you said that i googled this question but didn't understand the basic concept behind this, So here I will try to make it as simple as possible.

Bearing stress

Consider a rectangular plate with a rod inserted in it. The thickness of the plate and the diameter of rod are mentioned in the figure

Now, definition says that Bearing stress is a contact pressure between separate bodies. But the pressure always defined normar to the plane hence, bearing stress can be calculated as

Here,

Value of compressive load will be 20KN(10+10)

And area will be the projected area normal to applied load(i.e. thick.×dia.)

Crushing stress

It is the compressive stress developed at the contact interface, you can say it as a special kind if bearing stress which is localized and applicable only for the static condition.

Answer 2

Answer:

1] Crushing stress is a special type of localized compression stress which occurs at the surface of contact of two members that are relatively at rest. It is taken into account in the design of riveted joints, cotter joints, knuckle joints. ... 2] Bearing stress is a contact pressure between separate bodies
