Structural Analysis: K Truss - Method of Sections

[@alexandervanhell7427]

Why would you ever use the imperial system for calculating forces...

I would really appreciate it if you could make a video about how to convert uniformly distributed loading on the truss to point loads.

[@acs1789]

For the truss itself, the assumption is always point loads only and applied only at the joints (i.e. no point load applied to a truss member between two joints). If the truss supports a bridge deck, the deck itself may be considered a distributed load, but then that would have to be converted into point loads and then applied to the joints of the truss as appropriate.

What will be the force BF

[@ahmedsohail8924]

which members are in tension and which are in compression?

[@willhorin3065]

The convention is that when you draw the free body diagram, all members that are "sectioned" are in tension (seen at 2:15 & 4:30). Once all of the calculations are completed a positive answer indicated that this assumption is correct (i.e the beam is in tension) & a negative answer indicates that the assumption was incorrect (i.e the beam is in compression). Also, getting the assumption wrong ( a negative result) is perfectly normal & is nothing to worry about:)
