The cross-sectional area calculator identify the area for different varieties of beams. A beam is a very an important element in construction. The fill bearing member the bridges, roofs and floors in buildings are easily accessible in different cross-sections. Review on come understand exactly how to calculation cross-sectional area of *I* section, *T* section, *C* beam, *L* beam, round bar, tube, and beams v rectangular and triangular cross-sections.

A cross-section is identified as the common region obtained indigenous the intersection that a plane with a 3D object. For instance, think about a long circular tube cut (intersect) v a plane. You"ll check out a pair of concentric circles. The concentric circles are the cross-section of a tube. Similarly, the beams — *L*, *I*, *C*, and *T* — room named based on the cross-section shape.

We additionally know that the within diameter d is concerned thickness t and also outer diameter D as:

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

AC = π * (D2 - (D - 2 * t)2) / 4Similarly, the area of cross-section because that all other shapes having actually width W, height H, and thicknesses t1 and t2 are offered 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 find cross-sectional area?

Follow the steps listed below to find the cross-sectional area.Step 1: choose the

**shape**of cross-section indigenous the list, say,

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

**width**that the hole rectangle, W.Step 3: fill in the

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

**thickness**the 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 of 10 mm and also a thickness that 1 mm.

Step 1: pick the**shape**that cross-section indigenous the list, i.e.,

*Tube*.Step 2: get in the

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

**thickness**the 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 of cross-section shapes

*Did you know?*

*I*or

*H*beam is used generally in railway tracks.

*T*beams are found in usage in at an early stage bridges and also is used to reinforce structures to withstand huge loads top top floors the bridges and piers.

### How to calculate area the an i section?

The area that I ar with total width W, elevation H and having thickness t deserve to be calculation as:

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

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

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

The cross-section of a cube is a **square**. Similarly, because that a cuboid, the is either a square or a rectangle.
