Thank you so much sir, ur explanation is very nice ❤

Hi sir thank you for the video buat i have question, where can i get the given formula for young modulus?I understand that it is from derivation of : young modulus= stress/strain But i have trouble with getting the formula for stress and strain based on the experiment. And i am very confused as there are other different formula…Could you show me how to get the formula or at least a citation for it..
