However, the calculation is more straightforward if the combination (A+C)+ (B+C)-C is adopted. The final area, may be considered as the additive combination of A+B+C. Moment of inertia is considered as resistance to bending and torsion of a structure. The moments of inertia of an angle can be found, if the total area is divided into three, smaller ones, A, B, C, as shown in figure below.

Sub-area A consists of the entire web plus the part of the flange just above it, while sub-area B consists of the remaining flange part, having a width equal to b-t w. Area Moment of Inertia for typical Cross Sections II Definitions The moment of inertia of a tee section can be found if the total area is divided into two, smaller ones, A, B, as shown in figure below.

Area Moment of Inertia or Moment of Inertia for an Area - also known as Second Moment of Area - I, is a property of shape that is used to predict deflection, bending and stress in beams. Finding Z-section moment of inertia around x axisĪs a result, the moments of inertia of the each sub-area A, B and C around the axis x are: Second Moment of Area Calculator for I beam, T section, rectangle, c channel, hollow rectangle, round bar and unequal angle. Indeed, centroidal axis x, lies at a distance equal to h/2-t_f/2 from the parallel axis through the sub-area A centroid (and the same distance from sub-area C centroid too). Therefore, the parallel axes theorem should be employed for these two sub-areas (later in text, a short introduction on the parallel axes theorem is given). This axis happens to also be centroidal for the rectangular sub-area B, however the same is not true for sub-areas A and C. Let's consider here, the moment of inertia around the centroidal axis x, of the z-section, which is parallel to the two flanges. See our article on finding the moment of inertia of compound shapes for more details on the methodology. It is important however that the individual moments of inertia I_A, I_B, I_C, have to be determined around the same axis, before such a summation can be made. However, the end result should be the same if the methodology is followed consistently.

It is perfectly possible to split the given z-section in many different ways. The wanted moment of area I of the entire z-section, around a specific neutral axis, can be considered as the additive combination of I_A+I_B+I_C, of the individual moments of the sub-areas, over the same axis. Moment of inertia Rectangular shape/section (formula) Strong Axis I y 1 12 h 3 w Weak Axis I z 1 12 h w 3 Dimensions of rectangular Cross-section. Sub-areas B, C are identical in terms of sectional area, each having a width equal to b_f=b-t_w. Sub-area B accounts for the entire web (including the two small areas where flanges and web interesect), while sub-areas A and C account for the remaining flange parts, (A for the upper flange and C for the lower one). The moment of inertia of a z-section can be found if the total area is divided into three, smaller ones, A, B and C as shown in figure below.
