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 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,…
QUESTION BANK SIMPLE AND PRINCIPAL STRESSES CLASS NOTES Question bank help to revise and have better clarity and understanding of the subject. It helps in various competitive and other examinations. It increases lot of confidence. Practical problems are easily handled. Finally it helps in the design. SIMPLE STRESSES AND SIMPLE STRAINS Determine the diameter…
MATERIALS TESTING & FAILURES CLASS NOTES FOR MECHANICAL TESTING Perform tests on materials to determine the followings: 1.Strength of the material 2.Internal / external defects TESTING FOR STRENGTH Testing tells to use a material under a load in which it has the highest strength. Use a material under a tensile load If strong in…
