Describe the historical development of the mechanics of materials?

Why are pairs of materials more likely to experience thermal stress problems when they represent two different material classes?

You are a comparative evolutionary biologist that studies biomechanics. In particular, you are interested in how bone cross sectional shapes have evolved. You have discovered a rare (hypothetical) animal that has bone shapes similar to ours, but has solid, rectangular cross sectional areas. You conduct mechanical testing according to the parameters below and want to determine the: (A) moment of inertia; (B) reaction forces and moments at the fixed end O; (C) the stresses at points A, B, and C designated below, including the contributions of the different types of stresses at each point

How do heat treatment techniques like quenching and tempering contribute to enhancing the mechanical properties of materials in the field of mechanical engineering?

What is the significance of canonical form in mechanical engineering, and how does it contribute to the analysis and design of mechanical systems?
