I paid a lot of money for a statics class when its free and much more concise on youtube.... Professor Hanson is the GOAT. Hopefully other statics students will come across this gem of a channel.

I paid for collage to learn from youtube..

after the entire class bombing last week's quiz, including myself, I feel confident for this week. Thanks to your videos. You're a life saver!

Professor Hanson thank you for another classic lecture and master selection on the Centroid of a Volume using The Table method. In order to fully understand this concepts, I have done many Centroid problems in Statics.

5:03 you should first find the centriod of the rectangle then we add the horizontal distance from the origin right?

Godlbess you Professor Hanson. You are the GOAT!

It’s so useful:)

You're great,Sir

I understand better now sir thank you so much❤

This guy's fast math is insane

Helpful 👍

Thank you from Sweden

To find the volume of part 3, why 8×3×8=192 instead of 8×3×(8+3)=264 ... since on part 2 we added +3

At 7:54, would it not had to be added the 8 inches with the 3 inches to have the full base of the second rectangular prism?

No, he already calculated that part with volume num2, (1st rectangular prism as you say). so if of he adds the 3 inches it would be double counting.

Is this centroid outside the shape? If so, is that ok? Why?

I recommend you ask ppl to leave a like at the end. It will probably get you a lot more likes and more views by extension.

Jeff, for what it's worth to you.... I'm an adult learner who has just went to uni to study mechanical engineering bachelors level. I struggle to keep up with the lecturer on this topic, it is very fast paced, and taught at a kinda high level. I'm so happy to have found you, your teaching style has worked wonders for me. You make sense of all of it, and actually make it quite simple. You answer all the questions I need answered. I really enjoy your videos, and your 'dad jokes'. NEVER change!

please, I guess there is a mistake in the second rectangle you didn't add 3 with 8

why is it 1.5 and not 1 at 6:30 for x bar of shape 4?

look at the axis carefully, for shape 4, along the x axis you have a thickness of 3 , and the base of is along the y-axis, so in the x axis you have the 3, half of it is 1.5 .. you are most probably comparing it with shape 1, for shape 1 the thickness is along the y-axis, and the base is along the x-axis.

@@temwananimkandawire1245 Its not always the case, in this example the x bar for both shapes 3 and 4 is 1.5, if u go from the origin in the x direction you will find that the x centroid is in the middle (half of 3). Remember that the centroid of a 3d object has 3 coordinates, x y and z. and these 3 coordinates represent the center of the object.

😊

Wait so the centroid is not on the object?

Austin Frazier - doesn't have to be.. Consider the centeoid of a donut shape - it'll be right in the middle of the hole.

Or if you operate equipment and you have a forklift that swivels in the middle, your centroid will be outside of your cab. This gets a lot of new operators and they roll their equipment.

why say x is 10 for object 1? l mean you add 3,6,3= 12 from the origin...but nice video

The given shape of the object is a triangular prism when we are looking for the xbar for a triangle it should be 1/3 from its base vertex(I don't know what to call it) hence it's distance from the origin is 3+6+1/3(3)=10

You're great,Sir
