I've been struggling to understand the concept of Ashby Charts during my undergrad study, but your lecture makes it clear in half an hour. Great teaching, I hope you can enligth more minds like mine, thank you Sir!
Thank you! I'm glad you liked it! If you haven't seen it yet, check out the playlist for the course: MEEN 361: Advanced Mechanics of Materials: ru-vid.com/group/PL1IHA35xY5H5AJpRrM2lkF7Qu2WnbQLvS Thanks for watching!
when desiging my high powered rockets, i have to use a thrust to weight ratio in order to make sure it will meet my metrics. Also other things we cant control; environment. Rain, corrosion etc
Where can i put a line with a slope 2 for example. It can have any Y intercept. Is there any guide to pick a y intercept for a line selection with particular slope
I'm glad you liked it! I teach this course out of Shigley's Mechanical Engineering Design, 10th edition. There are many other more complete works regarding this topic; this video is really just an introduction to the idea of ashby charts. Thanks for watching!
How can i choose material of pipes that carries hot oils...materail should be corrosion resistant and stable at the high temp and pressure of comptessed oil
I use a Fujitsu T901 with a gen 2 i7 and 16GB of ram. It has a wacom digitizer. I use onenote 2007 as the note taking interface, and camtasia for screen recording and editing. Thanks for watching!
What would be the y intercept of that coupling line? because we can put that line easily in CES any where keepings its slope the same. Will we need to calculate the y intercept by putting some values?
I have noticed that too; I think its fair to say that you would have to estimate the Youngs Modulos, beacuse you need to have some parameter of resistence, to define the minimum of resistence the material needs to have, than you proceed to find the most efficient and manufacurable/acessable. I also have seen another video that teaches this. Im gonna send it to you, maybe it can help you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9RQkvcsRzbo.html
I need to obtain the index for a cylindrical beam under deflection, do you know how can I obtain it? the way I did I obtain S/Ro but you said that's for axial force, so Idk if it depends on the geometry of the material or I'm just bad with mathematics haha
You might check out this source: materialstandard.com/wp-content/uploads/2019/06/ASHBY99-Materials-Selection-In-Mechanical-Design-2Ed.pdf I believe something close to the derivation you are seeking can be found in chapter 5, and generalized further in chapter 8. Thanks for watching!
I teach this class out of Shigley's Mechanical Engineering Design, 10th edition. There are quite a few more thorough works out there regarding Ashby charts though. Thanks for watching!
You pick the slope of your guideline based on the kind of loading. Flexural has a different slope than axial and so forth. There are often guides provided along with the charts to help you know which slope is appropriate for various loading arrangements. Thanks for watching!
I'm sorry, I don't have resources to translate my videos to Arabic. I hope you find something that helps you! Maybe RU-vid will do an automatic translation at some point.
Please provide a timestamp for where I said weight and mass are the same thing. In the meantime, please understand that if gravitational acceleration is assumed constant (a very common assumption to make for items intended for use on earth) then weight and mass will scale proportionally to one another. Therefore for earth-bound components, designing for minimum mass is the same as designing for minimum weight.
