    STRENGTH OF MATERIALS-3

     STRENGTH OF MATERIALS-3   Thermal stress (σth) is there only when contraction due to fall of temperature is restricted——It is a tensile stress.=EαΔt Thermal stress (σth) is there only when expansion due to rise of temperature is restricted——- It is a compressive stress.= EαΔt Thermal strain = εth= σth / E=  αΔt Thermal stress in […]

    STRENGTH OF MATERIALS-2

       STRENGTH OF MATERIALS-2 TYPES OF STRAINS : six Tensile strain, compressive strain, shear strain, linear strain, lateral strain and volumetric strain. Symbol for tensile strain             =Є (epsilon)     = δL/L = + in nature Symbol for compressive strain = Є (epsilon)     = δL/L Symbol for shear strain               =γ (gamma), it is an angular strain. Linear […]

    Strength of Materials-1

       Strength of Materials-1 This subject tells which materials are strong in tension/compression/bending/torsion/buckling loads. 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 various kinds of forces/moments/torques etc. Tests help […]
