Mechanical Engineering: Trusses, Bridges & Other Structures (29 of 34) Tension vs Compression 3

In this video I will determine which member of a structure is under compression or tension using connections and rotations, example 3.

Next video in this series can be seen at:

World needs more teacher like just like you, sir

One comment I would make on this is that for new students when they see arrows going apart and you write compression it adds a element of confusion. but in truth when you look at the internals of each linkage it would be equal and opposite arrows which would then make sense -> C <- and <- T ->

I wish I had found this video a year ago when I was preparing for my Structural Consultant IV test. I didn't know that you could determine compression and tension so easily without using the method of joints or the section method. Thank you for the very clear explanation.

'And that's how it's done'. Thank you so much for this video. Very simple explanation.

Wouldn't the arrows for the forces be in the opposite directions? With tension that means the forces are pulling on the member, so I don't understand why the forces are pointing inwards. Same with compression, where it doesn't make sense for the forces to push outwards if the forces produced from the other members push inward on the beam.

You solved half of my life problems in single video.❤❤❤

[s.c.]

I like his style, the explanation too

[machxisgaming]

Explained very well in the most simplest manner. I understood it straight away.

[ziyadalmalki]

I spent more time on a different way and still did not fully get it. But I did with you, Thank you.

[DheerajSingh-solj]

Thanks alot sir for clearing such conceptual doubt

[aimanjamil]

can you please make calculation to determine the center tension.

[h.h.c]

Why are the arrows are drawn this way .. normally: . If the force tends to elongate the member, it is a tensile force (T), , why is 02:30 this shown as inward directed then? I guess it is the force withstanding that, but still a major deviation to how textbooks present the arrows.I actually like your perspective better, since it is thinking one step ahead, -) we regarding the counters.

[nicholasperuski]

Nice. Qualitative explanations are the best.

[rishikeshkrishnan]

Thank you sir. Learnt a lot from your teaching

[cerdo]

You are better than my teacher:)) Thank you for clear explanation

[Pollandland]

Brilliant! Very well explained with a good rule of thumb. Thanks!

I’m confused isn’t compression when the member is being squeezed and tension when the member is being stretched?

[kathleenrivas]

God bless you i thought indians would teach me this luckily i found your channel

[DavidMoore-brge]

Am i crazy or was there something beeping in the background? Great explanation your videos have helped me very much, i wish my professors were more like you

[ОльгаК-уп]

The video sound is pretty good, beyond my imagination
