AI Thread Summary
Calculating the thickness of a 35-meter steel bridge to prevent deflection is complex, as achieving zero deflection would require infinite thickness. The discussion emphasizes the need for a clearer problem statement, particularly if this is for educational purposes. For real-world applications, obtaining a mechanical engineering degree and working with a licensed engineering firm is essential. Participants suggest posting in a dedicated forum for homework help if the inquiry is academic. The thread concludes with a note that it is closed until further clarification is provided.

If i have steal bridge that is 35 meter long, 1,2 meter and 15000kg , how do i calculate the
thickness so that de bridge doesn't deflect?

That would require infinite thickness to achieve no deflection at all. Perhaps you could state your problem less vaguely.

Is this question for schoolwork? If so, what is the exact problem statement?

I understand that it is not possible to have no deflection. I have to design a gangway(a bridge between a ship and a platform), it has to be 35 meters long and at least 1,2 meters wide. I estimated that will weigh around 15000kg. How do i calculate how much it deflect?

You did not answer my question.

If this is for schoolwork, you need to post your question in the Homework Help, Engineering forum and fill out the Homework Help Template with the Relevant Equations and your Attempt at a Solution.

If this is for real-world work, you need to get your ME degree, pass the PE exam, and work for an Engineering company that carries liability insurance for the designs you work on.

This thread is closed until you can send me a PM to convince me that it should be re-opened.
 
Thread 'I need a concave mirror with a focal length length of 150 feet'
I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
Thread 'Where is my curb stop?'
My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
