that is, an axis at right angles to the plane of the cross-section, is defined as the moment of inertia of the cross-section with respect to the point of intersection of the axis and the plane. The polar moment of inertia may be found by taking the sum of the moments of inertia abo...
The mass of the strip = 2πrdrρ, where ρ is the density of material. In order to get the mass of an individual section, integrate the mass of the strip from r to R. The 2nd moment of the strip about the AA axis = 2πrdrρr2. To find the polar moment of inertia about the ...
Polar equations of conics are mathematical equations that describe the shape of a conic section, such as a circle, ellipse, parabola, or hyperbola, using polar coordinates. These equations are written in terms of the distance from the origin (r) and the angle from the positive x-axis (θ)...
