MECHANICAL ENGINEERING Interview Questions with Answers :- 1. What is the difference between isotropic and anisotropic materials ? If a material exhibits same mechanical properties regardless of loading direction, it is isotropic, e.g., homogeneous cast materials. Materials lacking this property are anisotropic. 2. What are orthotropic materials? It is a special class of anisotropic materials which can be described by giving their properties in three perpendicular directions e.g. wood; composites. 3. What is view factor ? View factor is dependent upon geometry of the two surfaces exchanging radiation. 4. What properties need to be considered for applications calling for following requirements : (i) rigidity (ii) strength for no plastic deformation under static load (iii) strength to withstand overload without fracture. (iv) wear resistance (v) reliability and safety. (i) Rigidity—Elastic modulus and yield strength (ii) Strength (for no plastic deformation under stati...
