*Explain the procedure for there constructing Mohr circle for an element acted upon by 2 tensile stress and shear stresses. Derive the expression for normal and tangential stress on a plane inclined at an angle of 0 to the plane of stress system and shown that the sum of normal stress in any two mutually perpendicular direction is constant 4.*

Rotating the stress state of a stress element can give stresses for any angle. But usually, the maximum normal or shear stresses are the most important. Thus, this section will find the angle which will give the maximum or minimum normal stress.

Engineering Mechanics 2 pp Cite as. In Chapter 1 the notion of stress in a bar has been introduced. We will now generalize the concept of stress to make it applicable to arbitrary structures. For this purpose the stress tensor is introduced. Subsequently we will discuss in detail the plane stress state that appears in thin sheets or plates under in-plane loading. This state is fully determined by stress components in two sections perpendicular to each other. We will see that the normal stress and the shear stress take on extreme values for specific directions of the section.

If it is a numerical question, it generally carries 2 marks and if it is a theory question, it may be 1 mark or 2 marks.

Principal stresses are maximum and minimum value of normal stresses on a plane (when rotated through an angle) on which there is no shear stress. Principal.

We will learn about principal stresses, planes of principal stresses and strains on principal planes. Practical examples of principal planes in actual components will also be discussed. Determination of the normal and shear stresses on a plane inclined on two planes on which stresses are given. Determination of the angle of the plane on which shear stress is zero.

*In calculus, you have learnt that when a function reaches maximum or minimum its derivative with respect to the independent variable becomes zero. Principal stress and principal plane.*
