Types of modulous of elasticity

According to Hooke's law, within the elastic limit stress/strain = constant. This constant depends on the type of strain or the type of force acting. Tensile stress might result in compressional or elongative strain, however, a tangential stress can only cause a shearing strain. After crossing the elastic limit, the material undergoes elongation and beyond a stage beaks. All modulus of elasticity are basically constants for the materials under stress. If stress/strain is x in elastic region and y in the region of yield, then

TRUE/FALSE TYPE QUESTIONS Modulus of elasticity of most of the materials decreases with the increase of temperature.

STATEMENT - 1 : The value of modulus of elasticity depends on the magnitude of the stress and strain and STATEMENT - 2 : A given material have different moduli of elasticity depending on the type of stress applied.
