The lecture is very good, the lecturing way of Mr. professor even better. this is excellent performance and easy to understand. Thank you very much Mr Professor !
You're channel is simply amazing. I have a professor who is not very inspiring and I have to say your use of examples and explanation of theory is great. Thank you so much, I will make sure to tell any of my friends struggling with machine design to check you out. Best of luck growing in the future!!
This is very much appreciated and helped out a ton. Wish I had you as a professor. Will definitely pass this on. (PS the first cycle yield equation your looking for is (6-49) =)

I will use this for my students. I will add some practical examples. Very good explanation. In my experience, students need some time and many examples of use to understand this diagram. Thanks, very helpful.

Hi Professor I have a question. When the midrange value (σm) is not given to us, how can we determine the min & max limit stress values from the Smith Goodman diagram?
I'm glad I could help! Here is a playlist of other lectures I give in that course in case you are interested: MEEN 361: Advanced Mechanics of Materials: th-cam.com/play/PL1IHA35xY5H5AJpRrM2lkF7Qu2WnbQLvS.html Thanks for watching!
Really great explanation. One of the best if not the best! Any lectures on Failure modes (Bolted joints and Threaded fasteners), Elastic instability (Buckling of columns), Pressurised cylinders (pressure vessels, compound cylinders) just wondering?? You have this way of teaching that makes this subject looks more interesting to the viewers and want to know more. Pretty sure there is this sentence in every comment "I wish I had you as a lecturer." Excellent and wonderful job
You are very kind! Thanks for the positive review! I do have videos that address most of those topics. (I don't have a buckling lecture recorded, but I plan to very soon.) Stay tuned, I'll post some links.

Hi, what are the practical sources of fatigue loads in rotor components. I'm assuming unbalance during rotation could be one of the source of HCF. Likewise, what could be the source for LCF?? Thanks in advance.
Professor, I have some problems and misunderstanding. (For infinite life)In case of fully reversing load, sigma max and sigma a is within endurance limit. When the load is repeated in nature, sigma max can go beyond Se(up to Sy)and sigma a should be within Se? Why should sigma a decrease, when sigma m increases in magnitude?

I am a mechanical engineer, so many of my videos have that kind of a flavor. There are many career fields open to mechanical engineers because it features a very broad base of study. Are you asking for video suggestions, or are you looking more for career advice?

Thank you for the great lectures. Is there a limit when the stress is applied so suddenly that it should be treated as an impact instead and is impact covered another lectures?
39:10 "We want to take the portion of it where the area is minimum". Doesn't the stress concentration factor already take into account the fact that there's a hole there? Shouldn't you then just plug in the nominal area of the rod, instead of the area lessened by the hole diameter?
No, you want to use the reduced area at the hole. The stress concentration factor accounts for localized increase in stress caused by the discontinuity in the continuum of the material (the hole). It does not account for the reduction in area due to the presence of the hole. You have to do that as I show in the example.
The lecture is very good, the lecturing way of Mr. professor even better. this is excellent performance and easy to understand. Thank you very much Mr Professor !
I am addicted to your lectures!
I suppose I have heard of worse things to be addicted to. :) I'm glad you are enjoying them!

Wow amazing explaining about fatigue and cyclic loading , i have seen best ever video which is explain deeply about fatigue

Hi Professor I have a question. When the midrange value (σm) is not given to us, how can we determine the min & max limit stress values from the Smith Goodman diagram?
How can we draw the load line on fatigue strength diagram?thanks

OK. Thanks for the reply. Also, thanks for the well delivered, easy to understand lecture :)
