This tutorial introduces the force method as a way to solve statically indeterminate problems. The force method is basically just a combination of the method of super position and any other method of your choice (moment area, double integration, tables, etc.). You separate the forces caused by the redundant reactions from the applied loads via the method of superposition, find the deflection caused in the "now statically determinate" structure caused only by the applied loads, and then knowing that in the real structure, there is zero deflection at the supports, use that condition to solve for the magnitudes of the forces that would cause a deflection at the point of application to be equal and opposite to the deflection in the "statically determinate" system. It's a nice method for structures that are 1 degree indeterminate. It's pretty clumsy for structures that are 2 or more degrees indeterminate, I would definitely recommend using another method (like slope deflection or three moment equation) for 2+ degrees indeterminate problems.

Looking for software? I highly recommend checking out SkyCiv. They make a full suite of online structural analysis software and tools that are useful for both students and professionals, including calculators for beams, trusses, frames, moment of inertia and more. It’s great for checking your work: bit.ly/skyciv-e4f

Thanks for watching, The Struggle Is REAL!
great job sir..Your videos are of a lot of help.
Glad to hear it... thanks for watching!!! 🙂
Can you do videos on stress, strain, torsion, or videos on manometer, bending stresses, second moment of area, udl. Pressure vessel, moments, flow regimes.
Hey I have completed some of those topics. stress/strain/torsion/bending/2ndmomentarea are here: engineer4free.com/mechanics-of-materials manometer is here: ruclips.net/p/PLOAuB8dR35oeOIPMOBH6hjwobuIJHPKSN moments are here engineer4free.com/statics I plan to publish videos on flow and a few other topics in the next few months. Cheers!
Engineer4Free what you should, is answer specific problems, this will. Give more context to what your doing and easier to understand.
My videos are usually either an explanation (like this video) or specific examples that use principles from the explanation. Here is a force method example: ruclips.net/video/mktQ61X-hGo/видео.html and here is another one: ruclips.net/video/V4C7XXYYwWY/видео.html they both follow the method that is laid out in this video that we are commenting on. It's a bit easier to see the grouping of videos by sub-topic on my website, for example: engineer4free.com/structural-analysis
