CORRECTION - At ⏰ TIMECODE 11:00 ⏰ Example 2 - The vertical member above the point load is in tension in all instances. It should be ‘T’ instead of ‘C’.
It depends on how loads are applied. Sometimes loads are distributed too. But the application of loads at joints is a modelling assumption for simplifying the structural analysis. The questions solved here taken The Institution of Structural Engineers Certificate course on Structural Behaviour.
@@cnjrq What are other load combinations? Roof framework and what other structural items produce loads on the members??? Assuming "roof framework" is ONE structural item???
@@TheAncientColossus the professor is here. In the video, I said compression by mistake instead of tension. It should be tension. Thanks for pointing this out. I’ll edit the video and cut that portion. I’m grateful for your feedback. It was a slip of tongue.
@@TheAncientColossus The snow load rests on the roofing sheet, which in turn rests on the purlins. The reaction of the purlins is transferred to the truss as a point load to the joint of the truss.

Thank you sir☺
It is my pleasure. I’m here to help.
@@DrJQureshi thank you sir
HOW to determine where the external load is applied? In practice, how do you pick LOCATION to analyze?
@@TheAncientColossus it will depend on where the roof framework is located for this particular case.

@@DrJQureshi WHO IS APPLYING THE LOAD IN REAL LIFE? GOD IS PUSHING THE STRUCTURE?
PLEASE.
11:00 INCORRECT. The forces are AWAY FROM joint. So it is TENSION?
WHAT IS THIS?
Yes, my mistake. I mistakenly said compression. You are right, it should be tension.

DESIGN WITHOUT THE ZERO FORCE MEMBER?
Why is the load ALWAYS APPLIED ON THE JOINT??? UNREALISTIC? OR USED IN REAL PROJECTS?
@@TheAncientColossus yes used in real projects. Trusses always carry loads at joints.
@@cnjrq Distributed snow load on top members? This is not joint???
@@TheAncientColossus trusses carry loads at their joints.
@@TheAncientColossus Golden Gate Bridge USA and Forth bridge Scotland use trusses with loading at joints. There are many other examples.
