This is very helpful. But one query from my side. We have calculated stiffness of bolt and stiffness of member but how we can say that the stiffness values are okay or not okay and on basis of what? Need to understand the details of how stiffness value is green for calculated joints. Please help.
Could you please suggest how to calculate stiffness of screw and members(no nut), in this case I guess we need to consider shank, unengaged thread portion and engaged thread portion for screw. And the frustrum diagram will be made from the last engaged thread and not the first engaged thread(grip length). Am I right.
Thank you for such a great lecture. Just one question, at min 5:42; why the radius of the washer is included? . The Bolt head and nut has the total sense to me, since those elements are the upper and lower limit of the zone.
Also, according to McMaster the value of D is 7/8 inches right? I got confuse at 9:37 where it is used a value of 0.75 inches. Thank you in advance for your clarification
The width of hexagonal bolt heads and hexagonal nuts usually report two values: between parallel, opposite faces, and between opposite vertices. The 7/8" might refer to the distance between vertices, which is of course, larger than between opposite, parallel sides (0.75" in this case). You can work with either, but you are right: McMaster does show the 7/8" dimension only. The process in the example is still accurate, regardless of the numbers used. Hope that helps!
Question from the real world: At 7:44 you say, "I would like to find a bolt that is suitable for this application." This doesn't make sense in the real world because literally any bolt can hold two plates together. Normally there is some force that is pulling the two plates apart. These forces are not taken into account in engineering books and I don't understand why. All I'm looking for is the pull out strength of any given bolt or threaded material. Seems like a simple request that I'm not finding anywhere.
Indeed,less boring lectures🥂
you explained this concept way better than what my professor did! Thank You!!
This channel is GOATED. Love how you present everything in a simplified manner.
I am not good at english, but I want to tell you.
You are so helpful for my school assignments. Thank you for your video!!
I like your writing!
your lecturs deserve th name its not boring and are the best plaese make more engneering studnts need it
Really helpful videos. Really concise and straight to the point
Thanks!
Saving my life for my exam tomorrow, thanks so much!!!!
Extremely useful for my machine components design class
Man is a legend
I love you for your channel name
This video helped me really thank you
Now we have the K for bolt and the members, What are these useful for? What are the applications?
this is beautiful

What software is used to create the sketches shown in the video?
Thank you for such a great lecture. Just one question, at min 5:42; why the radius of the washer is included? . The Bolt head and nut has the total sense to me, since those elements are the upper and lower limit of the zone.
Sorry, I don't get your question. Why is the radius of the washer included where? as part of what?
It would really help if you slowed down a bit. It's a little hard keeping up with the writing.
Thanks. I'll keep that in mind for future videos.
just stop the video and write ?

Appreciate the videos! however, you go way too fast and it would be helpful if you slowed down a bit :)
