concept problem There is a material and it is pulled by a distance by applying a force F. Tell me whether my intuitions is correct 1.In the world around we see materials of different shapes because the inter molecular forces bonds the molecules together in such shapes. 2.If one likes to break the material he should first exceed the inter molecular force(or cut the inter molecular force) 3.My question is what is the value of that inter molecular force. If i know that it is equal to "f" i will apply a force greater than "f" and then break the material. 4.How to calculate the inter molecular force. 5.Will my understanding of the above lead to the derivation of the stress & strain.
