Though my professor has been at this for 20 years, I don't get a word out of his lecture, figuratively and literally. You are perhaps my grade's salvation.
U take effort to send your knowledge to all the people who need these types of information... So, thank u very much sir.. Thank u very much. ☺️☺️☺️☺️☺️
Thanks for not just reading off slides. Writing notes is the best method of online teaching. My teacher just reads off slides and it's very ineffective.
Always thanks sir for wonderful lectures. Additionally may I ask to have problems based on lectures for practice and deep understanding to bring them in practicals?
@1400 min time for machinability cast iron is required and it has a 4 % of carbon and for hardness steel is required which has 2% of carbon . is this correct sir
@@metallurgist8326 The core is ductile in relation to the case. It is lower yield stress in comparison to that of the case. If the stress in the core exceeds its yield stress it will deform. But the design of gear should ensure that this does not happen under normal working stresses.
I've seen all your previous videos but I guess I have missed this concept. How does more carbon give more hardness to the material. Is it a thumb rule or is there any scientific reason for this. Thanks.

His way of teaching is the best I've ever experienced during my engineering.

thank you very much sir for your all the lectures on this subject . it is helping me a lot
Please sir upload more videos related to material science
Like
metal deformation process
Electronic materials for industry
Failure
Etc

As core is being ductile doesn't the shape get changed, when surface messes with other gears?
How hardness and ductility, 2 properties or combined in single component?
Or is there any other example for better understanding?

@@introductiontomaterialsscience ThankYouSoMuch Sir, for ur clarification.

Interesting sir 😍
You are genius guruji
Awesome class
Easy to understand the concept better than my ju college professors
👍👍👍👍
thanks
Love from Pakistan
Didn’t understand what you were saying much 😕
