• ### Moment of inertia & Polar Moment of Inertia

Moment of inertia and Polar moment of inertia Definition It is a property of a cross-sectional area to resist bending. Larger is the value of moment of inertia, lesser will be the bending. It is also called second moment of the area of cross-section.              Symbol Its symbol is ‘I’. […]

Bending Stresses PURE BENDING EQUATION M/I = σ/y = E/R Where M is the bending moment applied ( Maximum bending moment from BMD), Nm I = moment of inertia of the area about the centroidal axis, m4 σ is tensile or compressive stress at distance ‘y’ from the neural axis, MN/m2 y is the distance […]

• ### Theories of Elastic Failures

THEORIES OF ELASTIC FAILURES There are five well known theories of elastic failures. These theories explain material under simple or complex loaded condition is elastic in many ways and does not meet a failure but undergoes a failure in one of the following five ways. The material is safe in four remaining ways. For example, […]
