How to identify zero force members in trusses

This engineering statics tutorial explains how to identify zero force members in trusses. Please note that when I’m erasing members, I’m not “removing” them. They’re still there. I’m just erasing the ones identified to be ZFMs so the joints are less cluttered, and it’s easier to identify more ZFMs. Zero Force Members have purpose: for bracing, rigidity, and if the loading changes, the internal forces in each member will change, which means that different members will be ZFMs at different times. This problem is wildly simplified compared to a real life scenario, but is useful for teaching students about the concept and identification of ZFMs. If you found this video helpful, please consider supporting my work on Patreon:   / engineer4free   Looking for more statics tutorials?
