I have a weight of 6,kg to be lifted by a c-channel 6mmT x 65mmH x mmW with length of 2m. As I calculated, the c-channel weight will be 22kg. The c-channel then is lifted by a crane of 10,kg using sling T1 and T2 with weight 3,kg each.
With a 22kg of c-channel, it is so sure cannot lift the 6,kg. That means, I have to design a c-channel of 6,kg? However, how do I calculate the stress of the c-channel of how much it can withstand?
Will it bend? Will it break? Master, if your reasoning was correct your slings would have to weigh at least kg in order to lift the kg weight. Logically the C Channel has to be designed for the set load and not having the same weight. If it was you would need a crane for kg lift. Look at your vectors and forces and I am sure you can come up with some ideas how to calculate the loads on your channel!
The C-channel has to take that, also taking buckling into account. The channel has to take the axial load, plus the bending moment from the eccentricity of the connections. Kudos for knowing your limitations but filling in what you do not know by asking a public forum is wrong. On the other hand, we do clearly explain your assumption and we could then correct those assumptions. So you do have the potential to eventually get it right but not now.
Safely moving things with a crane requires proper training and certification. Your two dimensional drawing does not take at all into account that we exist in a three dimensional world.
To begin, choose a profile type and part number. From there input a length and the expected profile load. When you click "Calculate Deflection" the tool will provide several engineering specifications such as the moment of inertia and yield strength to determine the deflection.
You also have options depending on the expected configuration of your solution: whether there will be one fixed end, two fixed ends or the load will be supported on both ends.

Background: Hobby welder trying to design a utility trailer, no engineering background. Problem: I'm trying to determine if a 3" steel A36 "C" channel 4. Bending Stress 3" For horz shear stress, I don't know what the allowable value should be, so I'm clueless here. Where can I find the allowable horz shear stress for 3" Are my calculations correct?
Should I just give up and go back to playing with Legos? Hi Welder I agree with the way you've done the moment calculation, except you've been a little careless with units; the moment should be inch-lbs, not inches PER lb. I'm not sure I understand your shear calculation. I would just divide the lbs. However, when I look at your units, you've got area x depth on top divided by inertia x thickness on the bottom Do you know something I don't know?
Either way, the shear looks much too low to be the governing factor. Am I using the wrong formula? Also, is the 3" beam sufficient? Sorry about getting fast and loose with the units. College was 22 years ago, and I was a business major.
Yes, I looked up some references on the internet and what you've done is right.Beam bending formula, shear, moment, deflection plots for cantilevered beams and simply supported beams. This calculator is based on Euler-Bernoulli beam theory. The Euler-Bernoulli equation describes a relationship between beam deflection and applied external forces.
The simplest form of this equation is as follows:. The nice thing about this theory is that we can use these equations along with the boundary conditions and loads for our beams to derive closed-form solutions to the beam configurations shown on this page. The bending moment, shear force, slope and defelction diagrams are all calculated using the above equations. Of course, it is not always possible or practical to derive a closed-form solution for some beam configurations.

Calculating C-channel beams is a relatively simple procedure, as C-channel designs have been simplified into just two dozen types. This is due to the realities of steel manufacturing, which cannot create custom designs for every work order, and because standardization of C-channels makes steel-based construction projects that much simpler.
You will need calipers and a measuring tape to determine the dimensions of a C-channel beam to compare to a code sheet. This sheet will then give you all the values you need without having to do much math.
Measure the depth of the C-channel beam by placing a measuring tape on the flat long side of the beam in the center of the C. Even if the side is laying flat and is not vertical, the middle part of the C is still referred to as the height of the C-channel in order to simplify identification.
Write down that measurement in inches. Measure the width of the flanges. The flanges are the top and bottom of the C and are always referred to as the width measurement, even if they are not horizontal.
Write this measurement down in inches. Measure the height of the flanges by measuring from the inner valley of the C to the tops of the flange. Subtract this measurement from the width measurement to get the web thickness value in inches. Consult the C-channel code sheet.
The C-channel will first be separated by different depths, then by weight; since weighing a C-channel beam is impractical, match the web thickness values, since those are unique to each weight.
Once you have located the C-channel type you have, the sheet will give you the moment of inertia and section modulus for that C-channel beam.How to Calculate the weight of I-Beam?
