Influence Lines and Moving Loads - Intro to Structural Analysis

[@ChristoAnd]

I was looking at every video and my old textbooks and I couldnt wrap my head around this... I watch this vid and like half way through it clicked for me. Thank you so much, Prof.

[@StructuresProfH]

Glad it helped!

[@offthegridengineer2198]

Extremely helpful, as always! Thank you

[@ce.emir7]

amazing teaching,thank you verry verry and verry much🙏🏻

[@StructuresProfH]

You are very welcome!

In principle do we come up with segments using hinges. I have a continuous beam with no hinges

[@chidubemoleka8729]

I have some problems, I don't know if you could help me

[@chidubemoleka8729]

Some structural engineering problems that I need the solution

[@zhilyaismael8435]

thank you dear prof . could you please cane you give me some idea how it's come in in exam?

[@LSZ71]

maybe go through the statics real fast while you do all of this. might help people

[@StructuresProfH]

Good idea. Sorry it took me so long to get to this. This calculation sheet will lead you through the entire problem (all statics shown). drive.google.com/file/d/19rEG9XjrJwqRhD5Wc33PsTW7wzz9sDZs/view?usp=share_link

Prof. This is great. What app did you use to write the solution? I’m studying structural engineering and we will be submitting our assignments virtually so I need an online too I can use

The only thing I could not understand, is what a feet is?

[@StructuresProfH]

Ha, yeah US units are a little weird, but I promise they do work just fine for structural engineering, statics, and so on. I wouldn’t vouch for them for most other purposes, but feet and inches are a convenient scale for building construction. Anyway, a foot is a US unit of length. One foot equals 12 inches, which is 0.3048 meters, and is roughly the length of an adult human foot (hence the name). The thing with US units is they are NOT a unit system, a fact that is misunderstood by many metric-accustomed folks. It’s an assortment of historical units each developed and used for specific purposes, so there is no reason to believe they would ever “play nice” with each other. Like 1 mile = 5280 feet. Seriously, why? Well, because a mile was invented (long ago) for a different context; it measures land distances, while feet measures construction scale distances. Convenient conversion wasn’t considered because they were largely used in entirely different fields, and converting between the two was largely an academic exercise of little interest to most people who used these units. The point is, when used in their proper context (like feet, inches, pounds, kips, psi, and ksi for structures), everything works out similarly to using meter, millimeter, newton, kilonewton, MPa and GPa. When you mix in other US units from other industries or applications, things get crazy.

@StructuresProfH it was a joke but thanks for the extensive explanation. Good lecture by the way, I enjoyed it

[@StructuresProfH]

Well, you got me! It’s tough to tell sometimes because I get so many comments on US units that I had to set the record straight. I’m glad you found the video helpful!
