1. The problem statement, all variables and given/known data Determine the deformation of a composite bar is subjected to a centric force P. This is a general question. The composite bar is made of 2 materials. The top and bottom layer is material 1, and the middle layer is material 2. I cant think of a better way to describe how the materials are aligned but think of an icecream sandwich where material 2 is the icecream and material 1 is the outer chocolate pieces. Now is it safe to say that the deformation of the entire bar is going to be the same? Because both materials have different E values, but since the outer pieces are brazed to the center piece, deformation of the whole bar is 1 value correct? That being so, how exactly would I go about finding the deformation? Would it just be the deformation of the bar that causes the least amount of deformation?
