WebThe Equation for Moment of Inertia for Circular Cross Section: The moment of inertia for a circular cross-section is given by I= π d 4 /64 where d=Diameter of the circle. In a similar way, the moment of area of a pipe is given by I= π (D 4 … WebThe moments of inertia are then called the principal moments of inertia and the inertia matrix is said to be diagonal: I = ( I x x 0 0 0 I y y 0 0 0 I z z) The number of nontrivial inertia matrix elements that you must specify is in this case reduced to three—the principal moments of inertia.
