The General Form Of The Center Of Gravity Formula Is Very Simple.
The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The center of gravity is given by, y = (a1y1 + a2y2) / (a1 + a2) = (25×10/3 + 100×5) / (25+100) = 4.66cm. The moment of inertia must be calculated for the smaller.
In This Video I Give Step By Step Procedure For Finding Center Of Gravity Of T Section.by Applying This Method You Can Easily Calculate Any Example Of Center Of Gravity.

It Describes How Far From Centroid The Area Is Distributed.
Area of smaller rectangle = 12.5×5 = 62.5 cm. Area of large rectangle = 20×5 = 100 cm. Center of gravity for a t section, symmetrical about y axis.
In This Video I Have.
Last is to use a formula to calculate by graphic method. Where will be the centre of gravity of the t section shown in the figure? The center of gravity of a triangle is at the point where the three medians line.
Y Is The Measure Of Height Of T And The Centre Of Gravity Is.
C g × w = s x d w here, x is the distance from a reference line, dw is an increment of weight, and w is the total weight of the object. The moment of inertia of the area of the cross section of a structural member divided by the distance from the center of gravity to the farthest point of the section; In the given t section the center of gravity is on the base which is joining with the horizontal beam.
