What is that?

I have been quite curious about how structural engineers assess bridges when a heavy transport convoy (trailer + cargo) is being driven on top of them. I have seen different approaches, point loads or distributed loads (with some different criteria as well). I'm summarizing them in the picture...

I was just doing some road surveys nowadays in Ireland, and I found these signals (200m away from each other, one was doing downhill, the other one going uphill, so, not the same slope). It's curious one traffic signal is in degrees, and the other one in percentage. I tried to measure the...

Any clue what does it means the letter inside the red circle?https://files.engineering.com/getfile.aspx?folder=936ec1ba-1d80-4ebb-b606-6a76670c2538&file=technical_drawing_generator_2.png

Thanks for that. Do you have any other figures?

Thanks for the video. First time I see it. By any means, I was trying to find the reason behind the problem.

There are bigger pressure vessels being designed with 6, 7, 8, even up to 10 saddles for land and marine transportation purposes. So, if that case is indeterminate, how they calculated the loads to design the vessel accordingly?

Hello folks, Recently, I just posted here some words about the lack of understanding between vendors designing pressure vessels, and companies doing the transportation for installation on site. Here is a picture quite curious I would like to share. Why the vendor cannot design the vessel for...

cibachrome, 4WD will always win? Even when the surface has a pretty low friction coefficient?

You are right about that as well... usually performing (hands-on) seafastening is easier than doing cargo lashing for trailers (land transport) in terms of feasability.. About the lead time the purchase order is made, you are also right, but nevertheless, there should be a way to consider this...

From what I've seen on site while handling PV, some PV constructors are quite cheap, and dont want to be in these kind of communications because they don't have the manpower to deal with more calculations (this is the feedback I've got from this companies), and these PV constructors are being...

I was looking forward rather for your take or experience about dealing with this. I know there is a standard, but I think there is lack of interface between design team and transportation company.

I studied mechanical engineering, and my internship consisted in the thermal/mechanical design of a pressure vessel (TEMA/ASME). Curious thing is, that when doing so, I noticed the calculation of lifting lugs/trunnions/saddles were more or less, the last topic in the design of the vessel, and...

IRstuff.. Unfortunately, I do not have a video of it.

I'm just trying to find here the reasoning behind a situation we have seen several times, in several locations, with several trailers (same design). The trailer/equipment is not broken.
