## Centroid of I-Section

Centroid of I-section can be found easily with respect to reference x-axis because of section symmetry around y-axis. As shown in the example below; Example Find the centroid of I-section given below. Solution Step: 1 First divide the whole section into …

## Centriod of T-Section

Centroid of T-section can be found easily with respect to reference x-axis. This is so because T section is symmetrical about Y-axis. Centroid of T Section Example Find the centroid of T-section as shown below. All units are in cm. …

## Engineering Section

Engineering sections are the shapes that are most commonly used in the design of civil engineering structures like I-section, T-section, L-section etc… These sections are used in building columns, roof trusses, cantilevers, bridge girders, beams, stadiums, etc… some common engineering sections …

## Centroid by Moment Method

Centroid by moment method is based on the principal of taking moments about any arbitrary point. Centroid by moment method states that “When a number of coplanar parallel forces acts in a certain plane, then the algebraic sum of their …

## Centroid of Cube

Cube is a 3-dimensional shape whose length of each side is “L’”. Centroid of cube lies at a distance L/2 from each face of the cube.   Example Find the centroid of a cube whose length is 20cm. Solution   X= Y …

## Centriod of Right Circular Cone

Centroid of right circular cone lies at a height h/4 from reference x-axis. As shown in figure below;   Example Find the centroid of right circular cone whose diameter is 10cm and having height of 20cm. Solution Centroid of right …

## Centroid of Trapezium

Centroid of trapezium is bit tricky to determine. Because of different lengths a & b with having height “h”. Centroid of Trapezium Formula: Example A trapezium shape is given whose dimensions are; a = 6’, b = 8’, h = …

## Centroid of Semi-circle

Half circle is known as semi-circle. Centroid of semi-circle is at a distance of 4R/3π from the base of semi-circle. As shown in the figure below: Centroid of Semi-circle Formula:   Example Find the centroid of semi-circle whose radius is 10cm …

## Centroid of Circle

Centroid of a circle is very easy to determine. Centroid of circle lies at the center of a circle that is also called as the radius of circle from edges of a circle. As shown below. Examples  Find the center of …

## Centroid of Triangle

Center of gravity (centroid) of a triangle lies at a common point where the medians of geometric figures intersect each other. For determining centroid draw a lines from medians of each face to the corner of opposite sides. As shown …
