Strength of Materials

Best and easy way to understand and draw the Mohr’s circle   Mohr’s circle for stress on an oblique section of a body subjected to direct stresses in two mutually perpendicular faces and it is accompanied by a shear stress Detailed step by step procedure to draw the mohr's circle for a   body subjected to direct stresses in two mutually perpendicular faces ( When both stresses are of tensile nature ) Things to remember before drawing mohr's circle  👉tensile stress is taken as positive and compressive stress is taken as negative. 👉a pair of shear stress on // planes forming a clockwise couple is positive and a pair of shear stress on // planes forming a counter-clockwise couple is negative. 👉 you can use appropriate scale  for eg.  σ x (Megapascal) = σ x (centimeter)   1 MPa=1cm Step 1 . Draw a straight line length OB length equals to  σ x. Step 2 .  Mark a point A on line OB and Length of OA is equal to  σ y   . Step 3.   Draw a Perpendicular line AE and BF, length of AE a
