Thank you very much!!! You know what? Before clicking this video, I have been lingering around the internet for hours (reading articles, and watching videos), and in fact they all didn't work. Honestly none of those videos really explained the purpose of Young's Modulus and just persistantly brought up those generic formulae of stress and strain. Which confused me a lot, but your video summarised everything perfectly! It is so informative and even went extra for the syllabus curriculum, please keep up the good work ☺

Great video! Currently teaching this to my students. Will be directing them to this resource to supplement their work

At 5:00 you said they have different extensions , then how come would their graph be same ?

[@ohmy9261]

Because no matter what k value is it is always positive correlation

[@masamune4029]

Because no matter the extension or the force applied, all three springs are of the same material, so they have all the same property. Also, the graph is stress-strain, not stress-extension, so it doesn't matter if one spring extend more than another as long as they are made of the same materials.
Hope I answer your doubt :)
