## PRINCIPAL STRESSES MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS

PRINCIPAL STRESSES MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ help increase of knowledge and clarity about principal stresses. Principal stresses are simple stresses. These are either tensile or compressive stresses. Failure in a material takes place due to principal stresses, strains and energy. Thus MCQ help to apply fundamentals in real life applications. A principal…

## ELLIPSE OF STRESS & STRAIN CLASS NOTES FOR MECHANICAL ENGINEERING

ELLIPSE OF STRESS & STRAIN CLASS NOTES FOR MECHANICAL ENGINEERING   Ellipse of stress finds resultant stress and the angle of obliquity. In 2-D, it is ellipse of stress . In 3-D it is ellipsoid of stress. Actually all bodies are 3-D. All stress systems are also 3-D. But to make study easy to understand,…

## MOHR’S STRESS CIRCLE CLASS NOTES FOR MECHANICAL ENGINEERING

MOHR’S STRESS CIRCLE CLASS NOTES FOR MECHANICAL ENGINEERING Every item in nature is under complex loading. Hence, it is under complex stresses. But a material fails in a simple manner. It may fail in simple tension/ compression/shear/strain energy/simple strain/shear strain energy. Mohr’s Stress Circle is a graphical method to determine simple stresses and strains from…

## PRINCIPAL STRESSES-INTRODUCTION CLASS NOTES

PRINCIPAL STRESSES INTRODUCTION CLASS NOTES Every object in nature is under complex loading. Hence it is under complex stresses. But failure occurs in a simple mode. It may be in simple tension, simple compression or simple shear. Hence convert complex stresses into simple stresses. Simple stresses are principal stresses. To achieve this, use analytical or…
