see basically m an electrical engg...i knw the weight calculation its 6.8kg/meter as i ve been told...bt i need to knw how or any proof for that....it is required for the costing purpose of the electrical control panels...specifically for the calculation of base frame of the electrical control panel....

thanx guys for ur precious comments.....

Mensuration is pre engineering subject.So all kind of engineers should know it.

sir i disagree weight calculation ws not taught in the electrical engg or any pre engg education....if ur so sure then tell me that in which subject it was taught????and if u knw the ans to my question thn pls let me knw....cz i dnt have a clue abt how it is 6.8kg/meter????

W = Vρ; i.e, weight = volume x density. The volume part is from geometry; the density part is from elementary science.

In structural shapes, V = A_x-sec x L; i.e., cross-sectional area times length. Again basic.

Most catalogs of structural shapes state how many lb/ft, or kg/m, a shape weighs. For those, one simply multiplies by the length.

You can disagree.

Below are the links for class 10th science and maths syllabus NCERT Recommended, Please note after passing this, one has to spend two more years in school to qualify for entrance in engineering.

Science 10th syllabus

maths 10th syllabus.

That's what happens when you get stuck with the dopey metric system.

In the U.S., it's quite simple; for example, a C8x11.5 channel weighs 11.5 lb/ft.

Take the value of weight per unit length as available in any number of look-up resources, including the manufacturer's data sheets, and multiply by the desired length.

Is that soon enough (because Christmas 2015 is possible....)?

You are not solving your problem. what you should know is the method of calculating mass of any article in this world. and if you understand that you will not ask the same question again on any forum, Even if some one solve this problem for you, how about next time when you need to know the mass of a T section or an L section or a hollow pipe?

Here are the steps

1 Understand the various shape and geometries (two Dimensional)

2 Understand the various shape and geometries (three Dimensional)

3 How to calculate the area to two dimensional shapes and then volumes of three dimensional objects.

4 Undersatnd what the density is.(for different material)

5 Understand how to calculate the mass from volumes and density,

You need to search the CR4 Forum as this topic has been answered numerous times in the past few years by members. DUH

We don't need to reinvent the wheel every time one of you folks (especially clueless students) ask this question!

that information is usually embossed on all steel members in pounds per foot of lengh
