What is "Bearing stress" and Is it different from Crushing stress? If yes explain How? and When does an element come under Bearing Stress?

This question came to my mind while studying knuckle joint from a book of machine design in my current semester(IV) and something similar that I've studied earlier in my last semester in mechanics of materials:

I.) By GERE mechanics of materials TOPIC:Tension, Compression, and Shear

II.) By V.B. BHANDARI elements of machine design TOPIC: DESIGN AGAINST STATIC LOAD

See the two cases and try to observe the acting area and force being applied they seem to be the same...

    What source(s) do you have for these terms? How are they explained? – Solar Mike May 28 '19 at 19:04
  • Sources? What do you mean, please clarify. Not sure if I got you. –  May 28 '19 at 19:08
  • This looks like a [homework question](http://meta.engineering.stackexchange.com/q/121/1832). In order for such questions to be answered in this site, we need you to add details describing the precise problem you're having. What have you tried to solve this yourself? Please [edit] your question to include this information. – Wasabi May 30 '19 at 01:12
  • @SamFarjamirad are you sarcastic or serious? –  May 30 '19 at 13:06
  • @SolarMike these are the sources for these terms. and it is really shocking that you are asking for sources for these terms, haven't you ever studied them before? i am also adding the links to these books if in case someone down-votes my question saying "THESE PICTURES ARE NOT CREDIBLE SOURCES". –  May 30 '19 at 13:08
  • @hkishnani3 I may well have studied them before, but I have found that some, when trying to explain things in English, fail to get their meaning across as they have been known to misuse terms which leads to confusion. However, it is incumbent on you to make your question as clear and complete as possible, see https://engineering.stackexchange.com/help/how-to-ask The explanations for those terms in the books seems sufficient. – Solar Mike May 30 '19 at 13:12
  • please Note: I haven't highlighted (IV) CRUSHING FAILURE OF PIN IN FORK. in the third picture –  May 30 '19 at 13:18
  • @SolarMike I'm sorry for being rude. I understand. –  May 30 '19 at 13:21
  • I studied in German and French, both languages use almost similar terms and jargons which later were translated into english, i studied some international sources too again never seen these terms, by take a quick look, the crushing stress is nothing else but compressive stress i guess. I'll try to write a decent answer, if somebody else doesn't. – Sam Farjamirad May 30 '19 at 14:01
  • @SamFarjamirad thanks man! this means a lot. but I still want to know why was my question put on hold. –  May 30 '19 at 14:04
  • Because it was unclear, now it's better, i voted te reopen it. – Sam Farjamirad May 30 '19 at 14:06
  • The author , when describing the bar, bolt and clevis situation fails to differentiate between single and double shear - something covered in other mechanical texts I have read... – Solar Mike May 30 '19 at 18:25
  • @SolarMike how is this comment even related to my question –  May 30 '19 at 19:36
