SOM -SESSION 2

The resistance to elongation, induced in the body acts across the cross section of the body.

• Tensile stress

• Tensile strain

• Compressive stress

• Compressive strain

The resistance to contraction induced in the body, acts across the cross section of the body.

• Tensile Stress

• Tensile Strain

• Compressive stress

• Compressive strain

According to Hooke's law , Within elastic limit

• Stress $\alpha$ Strain
  

• Stress = Strain

• Stress $\perp$ Strain

• Stress $<$ Strain

Young's Modulus , E =

• Stress / Force

• Strain / Stress

• Strain / Force

• Stress /Strain

Elongation , $\delta l\ =\$ 

• PL/AE

• PL X AE

• PA/LE
