## POLAR & MOMENT OF INERTIA MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS

POLAR & MOMENT OF INERTIA MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS  MCQ increase the clarity and understanding. Moment of inertia plays its role in bending. Higher value resists bending. Highest value is for I-shaped cross section. Polar moment of inertia is important for circular motion as in shafts. Higher value of polar moment of inertia…

## THEORIES OF FAILURE CLASS NOTES FOR MECHANICAL ENGINEERING

THEORIES OF FAILURE CLASS NOTES FOR MECHANICAL ENGINEERING  Failure means breaking or deforming. Failure of ductile material is entirely different from the failure of a brittle material under same type of load. There are five well known theories of elastic failures. These theories explain material behavior under simple or complex loaded condition. It is elastic…

## MOMENT OF INERTIA & POLAR MOMENT OF INERTIA CLASS NOTES

MOMENT OF INERTIA & POLAR MOMENT OF INERTIA CLASS NOTES Moment of inertia is for a cross section. Larger value reduces bending. Polar moment of inertia is about the centroid axis. Larger value reduces torsional twist. Definition of Moment of Inertia It is a property of a cross-sectional area to resist bending. Larger is the…
