Type of Stress

Types of Stress-
1.       Tensile Stress
2.       Compressive Stress
3.       Shear Stress
4.       Torsional Shear Stress
5.       Bending Stress

·       Tensile Stress
v It is stress produced in a member because of pull type of loading.
v It is denoted byσt’








·       Compressive stress-

v It is the stress produced in a member because of push type of loading.
v It is denoted by  ‘σc’
·         Shear Stress –
v it is the stress produced in a member when the load in tangential to the cross-sectional area.
v Shear stress is denoted byfs’.
Double shear-
      (A=2Xπ/4d2)
·       Torsional shear stress-
v It is a stress which exists in rotating like shafts.
v It is denoted by ‘Fs’.

·         Bending stress-
v It is a stress which cause alongation of a member
v It is denoted by  ‘σb’
