Discuss why the design of your interaction, if simply implemented as is, may not lead to the ideal software design. Consider how the design of interaction and the design of software often have
different goals

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
