Trusses: Stability of Trusses- External Stability and internal Stability of a Truss

[@gzachewassefa3482]

it's awesome, Thank you Sir but I saw some note on internal stability which says 'm+r > 2j' is INDETERMINATE, Is this true ?

[@CivilThinking]

True

thank you very much sir!

Most Welcome! Let me know, if you have any suggestions!

Great explanation 👏

Thanks Appreciate that!

some reactions are parallel but not coinciding. Which option we have to take whether stable or unstable

[@CivilThinking]

In that case the truss will be unstable because since the reactions are parallel means they are only in one direction. What will stop the motion of truss in other direction? Nothing. That's why it will be unstable.

[@santhanakrishnanramraj8747]

But in the same case, reaction force does not coincide. The statement says, if reaction force are not coinciding it is stable.

[@santhanakrishnanramraj8747]

Now I understood. Good 👍
