Why is tension the same everywhere in a rope

This engineering statics tutorial explains why tension is the same everywhere in a rope. Rope/cable problems are very common in statics, and higher level structural engineering problems. The key takeaways from this video are that for statics problems involving ropes, that the ropes can only be in tension, that tension force is the same at all points of the rope, and that the tension is always inline with the rope itself.

It's all these small concepts in science that makes it all the more interesting.
Thank you.
Really appreciated this kind of content on TH-cam.

[@Engineer4Free]

Thanks Biswayan. Glad you appreciate the small details as well as the big picture :)

[@akhilesh1466]

Really Nice ....These small concepts make the bigger things..

[@Engineer4Free]

Thanks Akhilesh!! Learn the absolute basics really well and the rest will come easier! The full playlist is here too: engineer4free.com/statics

[@swastiksamal9515]

Thanks, Brother.👌

[@Engineer4Free]

You're welcome!! =)

[@sakshishukla41]

wouldn't the pulley (disk) extert a normal force, and that would alter the tension in the string?

[@LovelyNomad2024]

you are ANGELNEER ;) ILOVED YOUR ALL CLASSES.

Thanks Derya!! 😇

If possible can u please Make a video..On :
"Why the tension Of a spring with some mass attached to blocks at both ends kept horizontally on a table Not same at all points????"

[@catsonair9432]

Wouldn't this not be true if the rope has a mass of M ?

[@heavenlyknighthood]

I am sorry to say but I really don't see the point to making a free body diagram. I can not see the benefit of it or the help it gives, why not just use the system.

[@Engineer4Free]

Later in your studies, you will encounter more complex systems. You will need to draw separate FBDs for various points or members. So at this level, you need to get used to drawing FBDs, even if the system is simple.

[@heavenlyknighthood]

@@Engineer4Free I will take your advice on board and i will try to start drawing FBD more often. Again thank you for the prompt reply.

[@Engineer4Free]

​@@heavenlyknighthood No worries! I often just draw the forces in a different colour on top of the original diagram to speed things up if I'm just doing it for myself, but for assignments/exams etc many professors will request that you actually draw a dedicated FBD, so I try to stay proper in the videos 👍
