Virtual Work - indeterminate beams - concept

[@eliasvusi3451]

Thank you, why is the deflection due to real load uses moment from virtual unit load?

What about a beam fixed on both ends?

[@ProgrammedMechanics]

I don't have a video explaining how to handle more than one indeterminacy with a force based method. Have a search for "flexibility matrix".

[@husnajaffry9688]

what happen if there's settlement happen at point A and B?

[@ProgrammedMechanics]

the beam in this example has only one degree of indeterminacy, so only one support is removed. I don't have an example for multiple indeterminacies, search for "flexibility matrix".

[@mohamedsherif4096]

nice tutorial, but how is that different from the force method?

[@ProgrammedMechanics]

virtual work is a force method

[@marshallmather2638]

Please could you do another video on multiple loadings as some of the steps are a bit ambiguous.
