- Want to see more mechanical engineering instructional videos? Visit the Cal Poly Pomona Mechanical Engineering Department's video library, ME Online: www.cpp.edu/meo...
This lecture series was recorded live at Cal Poly Pomona during Spring 2018. The textbook is Beer, Johnston, DeWolf, and Mazurek, "Mechanics of Materials (7th edition)."
Started watching this series last month. I'll come back here once I've graduated.
Yeah sure you have to come again.. I was very weak at this subject i finished my engineering major, now and after 5 yrs since my graduation relized why am very weak in my major.. This subject is very useful to deal with every aspects of engineering.
Did you graduated ?
can you recommend videos for 3rd semester mechanical engineering' diploma
These series with Dr. Mohammad Izadi are extremely useful.
Thank you CPPMechEngTutorial for publishing such videos
You're welcome.
Best introduction I have ever seen.
"Every body understand what i am saying"...catchphrase of proff izadi
Or “Is that correct or not?”, I’d sometimes count how many times he said it in a lecture. Sometimes he’d get well over 20 times per lecture
I've never thought of the center of mass expression as involving the moments of the mass elements. It should make total sense, intuitively; an object balances on its center of mass -> it has no tendency to rotate -> it has no net moment.
i think the lecture series of mechanical engineering content of this quality..is only found here..thanku..dr.izadi and cpp
:D
Hello, Can you show about textbook for Strength of materials for this course.
Is this same as solid mechanics ?
Best lecture series were ever taken by me😍😍😍... Thank you@cpp...very grateful...
Genuinely wish you were my professor. My professor is so terrible and you're my savior!
Very sweet handsome kind comfortable man. I wanna hug him plz 🌹💋❤️
47:47 i think it should be 3/4 not 3/5
Thank u
Great source , extremely informative
Since college times and even after graduation times i still do not know what is meant by first and second moment of inertia practically/ in real live!! What i know is moment of inertia as the definition in newton laws (tendency of a body to resist a sudden force pla.. Pla.. Pla).. Also i know moment mathmatically force x perpendicular distance...i know its a feature of section but i dont know its meaning from its name 😢😢😢😢..
• In general any moment of inertia is the ability of body or structure to resist against its change of state of motion or structural shape.
For e.g.
1. Mass moment of inertia (kg*m^2) is measure of how body will resist the change in its state of rest or motion against the external applied torque for rotation. Its moment of inertia depends on three factors -
(i) Position of axis of rotation & centre of mass,
(ii) Orientation with axis of rotation & external force relative to body.
(iii) Distribution of its own mass relative to axis of rotation.
Mass moment of inertia defines how fast will body response to the applied external torque in rotation.
2. Area moment of Inertia or second moment of inertia (in m^4 or m^2 * m^2) is measure of resistance of cross section of structure against the changes in shape or orientation of c/sn caused by induced stresses like bending & shear as a result of external transverse loads.
It is defined for axes passing through centeroidal point of cross section.
Area moment of inertia matters for induced stresses due to external transverse loads on structural beams & axial loads on columns due to buckling.
Thanks for these lectures.
Which book is Sir following?
I don't understand the last part of centroid (25x200) what about 12.5
Forgot I suppose.
very helpful for my upcoming online class on theory of structures!
Did it go well?
Sir i want one difficult question and that question answer in strength of materials PhD level student also can't give that answer pls reply sir
I am enjoying my summer for sure thanks to you üstad ( teacher)
hahahah
What's your native bro?

15 minutes in and I'm loving it. It's been years since I took a materials course so naturally I am struggling in Materials II. Nice crash course to remind me off all I need in this higher level class.
Hopefully you made it through your course.

Great learning source materials . Thank You all for this great relearning opportunities. Hope you keep posting other civil engineering materials . Stay safe and healthy.
This is a mechanical engineering channel. :) But many concepts overlap between the disciplines.
good base for structural design thanks
Where could I find the solution manual?
Qx the first moment of area about x axis. :)
Design, find the centroid first and then find the moment of inertia with respect to the axis that pass through the centroid.
Q above and Q below must equal and opposite.
I am in love with your lectures sir................so good. This course is for polytechnic student or for bachelor of engineering students.Is there any certification of these courses by this program. ... .thanks
I am a student that has had the great privilege of sitting in Professor Izadi's class! This class is for Mechanical Engineering students pursuing a Bachelor's of Science degree in Engineering. The university is a polytechnic one.
The mechanical engineering program at this college is ABET-accredited
@@ankursolanky4129 thanks

Dr.Izadi, thank you, sir !!!
Thank you for your channel
You're welcome.
Sir you are not mention the book edition and Ritter name

i love you man
Awwww.

Great material
Thank you for your channel.
I want dr.izadi's research gate site please
How did you come up with the 3/5?
what text book would you recommend to use with these lectures?
Please see the information below the video for textbook information.

dr. izadi is iranian so proud of him
i had been through different courses related to som from paid courses to famous one but none of them worked for me, now i am here, i hope this one clear out my concept.
Let us know if it helps.
Where can i find the handouts?
You can find them here: www.cpp.edu/meonline/strength-of-materials.shtml
Thank you very for your channel, could you please rise the handout of the lectures?
thanks a lot of lecture
I'm from Ethiopian so this discussion helping me I'm grateful for lecture
l love the class for today
is there anywhere we can access the handouts given in his class?
www.cpp.edu/meonline/strength-of-materials.shtml
please, in the static course you used to show the homework that the professeur selected from the textbook, but now he just speaks about them and I don't find them writing on the bord. Could you please tell me which problems he selected for the homework ?
Did you check out this site?

@@CPPMechEngTutorials Thank you so much ! I found them on the syllabus
still awesome!
is it helpfull for gate ???
Yes or no, correct or not
yes or no
yes or no
Yes.
what a great man
I love this discussion 💕
Very good ustaad.
مایه افتخاره
Just saw that this was only recorded last quarter. Good stuff, since I'm talking 218 CAP this quarter. Is the plan to record lecture series for all ME classes? And what about other classes, like math? These videos are invaluable
We are glad you find the videos useful. At the moment we don't know how this project will evolve over time. It is possible we will record every course, but it would take us many years to do so.
Yea they're all on ME online! www.cpp.edu/meonline as for math classes, I'm not sure.
This channel only contains mechanical engineering-related content.
thank you professor for all lectures.
:D
@@CPPMechEngTutorials what is so funny?
@@alperenkurt2892 Just a happy face.
I got a C in statics....
I wasn't that bad...but I was just so numb during exam and couldn't think straight....That affected my whole semester, I got real depeessed.. My cgpa dropped down from 3.76 to 3.54....Everything changed including my dreams....I wish I had gotten another chance to sit for that exam...
Buddy don’t be upset, it’s just one test you could do the rest better, have you finished this series of videos?
💜
awwww.
one day you may be on edx.org
They would be lucky to have Dr. Izadi. :)
For sure I am sorry my English what meant was this is a great course and great teacher ....
@@CPPMechEngTutorials ok

Best Chanel for Mechanical Engineering students. Much respect to you! Keep going
We're trying.
@@CPPMechEngTutorials Are you going to add structural mechanics course?
@@aleksandrekobeshavidze559 There are no plans at this time for a course like that. Typically, that would fall under civil or aerospace engineering (depending on the structure).
thanks!!!
