with this question, I am not sure whether its ok to find the compression of each of the rods separately first, then add the answers together to get the combined length decrease becuase i couldn't get the right answer that way...and i don't know if its ok to add the 2 young's modulus for the 2 materials together and then treat it as one material...can anyone help me out here?
