    STRENGTH OF MATERIALS INTRODUCTION CLASS NOTES FOR MECHANICAL ENGINEERING

    STRENGTH OF MATERIALS  INTRODUCTION CLASS NOTES FOR MECHANICAL ENGINEERING Strength of materials tells which materials are strong in tension/compression/ bending /torsion/buckling. Hence depending upon the application, one can select the material for that application. Application includes chair, table, rod, shaft or any item one can think of. The selection is possible after performing tests under […]

    MATERIALS OF CONSTRUCTION AT CRYOGENIC TEMPERATURES

      MATERIALS OF CONSTRUCTION AT CRYOGENIC TEMPERATURES   All materials do not work satisfactorily at cryogenic temperatures. Properties undergo a tremendous change from room temperature down to cryogenic temperatures. Mechanical, electrical, thermal, and magnetic properties are most affected. At cryogenic temperatures, properties of concern include permeability, thermal conductivity, specific heat, linear thermal expansion, thermal expansion coefficient, […]
