The cross-sectional area calculator determines the area because that different types of beams. A beam is a very critical element in construction. The fill bearing member of bridges, roofs and floors in structures are obtainable in different cross-sections. Check out on to understand just how to calculation cross-sectional area that *I* section, *T* section, *C* beam, *L* beam, ring bar, tube, and also beams v rectangular and also triangular cross-sections.

## What is a cross-section and how to calculation a cross-sectional area?

A cross-section is characterized as the common region obtained from the intersection the a aircraft with a 3D object. For instance, consider a long circular tube cut (intersect) with a plane. You'll watch a pair of concentric circles. The concentric circles room the cross-section of a tube. Similarly, the beams — *L*, *I*, *C*, and also *T* — room named based upon the cross-section shape.

We likewise know that the inside diameter d is related to thickness t and also outer diameter D as:

d = D - 2 * tTherefore, the area the cross-section becomes:

AC = π * (D2 - (D - 2 * t)2) / 4Similarly, the area the cross-section for all other shapes having actually width W, elevation H, and also thicknesses t1 and t2 are provided in the table below.

Cross-sections SectionAreaHollow Rectangle | (H * W) - ((W - 2t1) * (W - 2t2)) |

Rectangle | W * H |

I | 2 * W * t1 + (H - 2 * t1) * t2 |

C | 2 * W * t1 + (H - 2 * t1) * t2 |

T | W * t1 + (H - t1) * t2 |

L | W * t + (H - t) * t |

Isosceles Triangle | 0.5 * B * H |

Equilateral Triangle | 0.4330 * L2 |

Circle | 0.25 * π * D2 |

Tube | 0.25 * π *(D2 - (D - 2 * t)2) |

## How to uncover cross-sectional area?

Follow the steps listed below to uncover the cross-sectional area.Step 1: select the**shape**of cross-section from the list, say,

*Hollow rectangle*. An illustration of the cross-section and the related areas will currently be visible.Step 2: get in the

**width**the the hollow rectangle, W.Step 3: to fill in the

**height**the the cross-section, H.Step 4: Insert the

**thickness**of the hole rectangle, t.Step 5: The calculator will return the

**area of the cross-section**.

## Example: using the cross-sectional area calculator.

Find the cross-sectional area of tube having actually outer diameter the 10 mm and a thickness the 1 mm.

Step 1: select the**shape**of cross-section indigenous the list, i.e.,

*Tube*.Step 2: get in the

**outer diameter**that tube, D = 10 mm.Step 3: Insert the

**thickness**of the tube, t = 1 mm.Step 4: The area the cross-section is :AC = π * (D2 - (D - 2 * t)2) / 4AC = π * (102 - (10 - 2 * 1)2) / 4 = 28.274 mm2

## Applications that cross-section shapes

*Did girlfriend know?*

*I*or

*H*beam is used extensively in railway tracks.

*T*beams are discovered in usage in early on bridges and is provided to reinforce frameworks to withstand big loads ~ above floors the bridges and also piers.

### How to calculation area the an ns section?

The area that I section with total width W, height H and having thickness t can be calculated as:

Area = 2 × W × t + (H - 2 × t) × t### How to calculation area of one T section?

The area of a T section with total width W, elevation H and also having thickness t can be calculated as:

Area = W × t + (H - 2 × t) × t### What is the cross section of a cube?
