Dr. Hanson is literally such a supportive and helpful professor. Thank you for your videos! At my school, my engineering professors can be really intimidating and often advise students to change their majors after making even the smallest mistakes, which is really frustrating and not supportive. Thank you for making a positive difference!!

One of the best professors I have ever seen in my life keep it up sir love from India 🇮🇳

8:02 Only KZread math tutor I've ever seen to diss 90s and 2000s music and then lead that into a formula lmao.

"You like to move it move it" made my day 😂😂

I'm reviewing subjects for PhD qualification and your teaching is really helpful, thank you.

Great addendum to my teacher's class. Thank you for your care for your students and your sense of humor, Professor Hansen.

*Hanson. Sorry.

He is a king among men, sharing this information with is in a way that can actually be understood. 👑

We going for speed! Thanks for speeding things up, Dr. Hanson.

Prof. Hanson: "what's the greatest generation of music?" Me: "The 60's!"

I swear you are one of the best doctors i have ever seen, your way it is so easy and also entertainment, i love you dr, your son from Saudi Arabia 🇸🇦

DR. Hanson, thank you for an excellent presentation of the Parallel Axis Theorem and the Area Moment of Inertia.

As an educator myself, I must compliment you on your videos. They are great! You break things down beautifully. Thank you for the videos and everything you do!

Came here to say this!

You’re helping me so much with my engineering degree, you’re an amazing teacher!! Much love from England !

Lova ya Jeff Hanson! Been saving me for the past 3 years of engineering lol

You are awesome at explaining! You are easy to follow! Love it!

Great video; taking design courses rn, so this is vid is a terrific refresher!

Thank you Dr. Hanson! Your videos are helping me prepare for the PE

how did you know we were going to answer 90s music

Dr. Hanson has gotten me through my BSCE, FE Exam, and now my PE exam!! Keep studying, it gets better!

You are the best teacher I have seen in my entire Life.😍👍🏻

I've learned more from this youtube channel than the campus professor I'm paying thousands of dollars to teach me. Greatly appreciate the concise, well spoken lectures.

You saved today, I will be forever grateful!

I'm nearly at the end and actually really excited to see if you get the same answer twice.

Really excellent presentation. I especially appreciate when you explained the significance of moment of inertia so we understand WHAT the number means (higher moment of inertia = higher resistance to bending = stronger shape). Thank you

It really has nothing to do with inertia. It is named "area moment of inertia" because the calculus that defines it is very similar to the calculus that defines moment of inertia in rotational dynamics. The essential difference is that the differential term is area, rather than mass. Second moment of area is a more accurate name. Moment in general means a quantity multiplied by a distance from an origin, added up with that value throughout a system. Second moment means that distance is squared as you calculate it. It comes about because fibers contribute to resistance to bending in two ways, that are both proportional to the distance from the neutral axis. The first way is that the fibers are stressed in proportion to how far they are from the neutral axis, and the second way is that the fibers contribute to resisting the applied bending moment with a "lever arm" that is the distance they are from the neutral axis. When you have a composite assembly of materials that form the beam, Young's modulus also plays a role in each term that gets added up. Beams of a uniform material put Young's modulus as a constant out in front when calculating deflection, because it is term that is the same for all fibers. Composite beams need to include the granularity of how Young's modulus applies to each portion of the beam specifically.

Thank you for this free content!

Thank you so much! That 80's music joke really helped me on my homework!

You're the best! I owe you my grade - thank you!

Love your lecture... serious change the way I understood this topic ... Thanks 💯💯

Big help, thank you sir👊🏿

Thank you a lot for the video!

Thank you so much this is really helpful 🙏🏽.

Dr Hanson u reli help me get through this semester exam on this topic as I am not good at maths beforehand. Thank you so much!! u r funny and easy to understand even though I come from Hong Kong.

Exactly what I needed. luv u sir. thanks

My lecturer has miss some important and key concept that have explained by you in this video! thanks to have your video !

Now that's what i'm talking about! Was very helpful, Thankss

You are really a very good teacher Prof!!! Lord bless you!

Thank you so much sir for sharing your precious knowledge.

You saved me all the way to my 3rd year in college :D , please consider doing theory of machines , i need u in my life xD.

You just solved my assignments for me. Everything is clear like the voices of 80's female singers 😅 Thank you 😊

Love your lessons sir, keep it up :)

You are amazing dude, I am here doing Engineering at uni and honestly you explained it better than my tutor

I love you man

Thanks 🌼

thanks sir Jeff Hanson

Sir very great teacher

thanks

What a great teacher, I thought the 80s joke was funny!

Thank you for explaining (d)

veryyyyyyyyy helpful!

Thank u sir😇

it makes much more sense when you teach it. thank you!

Claims 80's music is the best generation of music, immediately references a mediocre song from the 2000's lol. God bless you sir your videos have been awesome. (Do heat transfer next!)

80's is correct MR!

Can you be my statics professor please? Mine sucks so bad and they have a Phd in Structural Engineering.

LOVE U

static of inertia of composite beams pls? I can learn more if youre the one explaining it. thanks for all the vids

The idea behind composite beams, is that you use E as a factor to make a weighted average when finding the neutral axis. And rather than only working with the 2nd moment of area as a purely geometric property, you are adding up E*I for every sub-material within the composite. So your centroid is more like a center of elasticity and area, than purely a center of area. And your 2nd moment of area, is more like a 2nd moment of elasticity and area.

may i know why do we want to move the centroid from the smaller pieces to the center of the big pieces , sir

The parallel axis theorem can be used for moving to and from the center of mass, or for this kind of "moment of inertia" rather, the centroid (center of area). For moving to the centroid, you subtract A*d^2, and for moving away from the centroid, you add A*d^2. You can use it to move between two axes that have nothing to do with the centroid, but you would deploy it twice, with the centroid as a waypoint in this calculation.
