Force method example #1: one degree indeterminate

Check out www.engineer4free.com/structu... for more free structural analysis tutorials. The course covers shear force and bending moment diagram review, method of superposition, moment area method, force method, displacement method, slope deflection method, and 3 moment equation.
TYPO: At the very end, I miscalculated Ma. I wrote 5.6 kNm when it should in fact be 5kNm. Sorry, don't know how that happened.
This tutorial goes over a force method example problem that is one degree indeterminate.

    I can't believe the video lectures I'm paying Penn State 1700 dollars to take for a 6 week structural analysis class pale in comparison to the videos you produce. You're seriously a blessing!!!

    Hello. I want to thank you for all the hard work you've put in for us. I am currently in the final stages in my GSA coursework for my UCL Civil Engineering course, and this video helped me get AMAZING results. For anyone hesitant about the quality of this video, I can assure you that this video is a LIFE SAVER. Thank you Engineer4Free, and i will no doubt be buying all your merch and repping it in classes haha :P once again, thank you. May the FORCE be with you!

    What if I have a situation where the structure is similar to yours, but the P load is not on the end of the beam? I'm unsure which equations to use when the P load is not on the end. The structure is still fixed at one end with a roller on the other (that we remove) and there is still a distributed load downwards across the length of the beam. The only difference is that the fixed end is on the opposite side that is on in regard to your structure and there is a point 20 m from the left side where the P load is applied, then 10 m to the right end of the beam where the fixed end is.

    So that’s an overhanging beam. Here’s a video with an overhanging beam example: www.engineer4free.com/4/shear-force-and-bending-moment-diagram-practice-problem-7 the example is statically determinate but worth watching to get the idea. You just treat the beam section between the supports as if it’s simply supported, but instead of having zero moment on the end with the overhang, it’s going to have an internal moment equal to that point load out on the end times the distance to it. Actually, I’d recommend checking out the superposition section of engineer4free.com/structural-analysis because the force method is actually just what we call when we use the method of superposition for statically indeterminate structures. Hope that helps

    You can use method of suoerpoaition + table for multiple point loads. See the third row here for the formula that you'd need to apply twice: engineer4free.com/extras/beam-slope-and-deflection-table

    their is but you can find it after finding the reaction at the redundant support. so first apply force method once you have your reaction use it to find the moment about A

    @@flowmaticgaming4892 but how would you find it without first finding your support reactions😅 like yeah you can find it but after using that moment to find the support reaction of the redundant support your moment would just change again. So I’m my opinion it’s easier to just find the reaction first then use it to find the moment.

I have a homework, and I should do it with the Force method.It is 3x staticly indeterminate. Could you please take a moment and guide me how is the easiest way of doing it.
