The polar moment of inertia is represented by “ J”. Polar Moment of Inertia and Its Application I have an article on How to calculate area moment of inertia for different sections. There are different formulas for calculating different cross sections. Also for calculating the maximum deflection angle and distance of different types of beam, you will be required to use the area moment of inertia. So, if you are solving a beam problem, or treating any other problem as a beam problem, then you have to use the area moment of inertia (I). The area moment of inertia is the property of a shape and is used in the beam deflection equation:įrom the equation you can see the stress value ( σ) decreases with the increase of the area moment of inertia (I) or in other words it resists beam bending or deflections. Interestingly, mass moment of inertia also is represented by “ I” though some difference between the mass moment of inertia the area moment of inertia exist. The area moment of inertia is represented by “ I” in calculations.
