Hi all,
We have a basic "simply" supported beam, if you can imagine a beam 5000mm long with supports at (b) 3000m and (c) 5000mm - the load is applied at (a) 0mm - ie a "simply" supported cantilever.
The thing is the supports are not strictly simple but are not fully rigid. The support at (b)will prevent some rotation but not all. As in most cases in the real world I would normally disregard this and approximate the beam is simply supported for worst case for reactions etc.
The issue is I need to get some quite accurate values for the reactions at thr 5000mm support - we are running a little close to allowable loads.
I have a feeling this may not be that easy, any suggestions?![[bigears] [bigears] [bigears]](/data/assets/smilies/bigears.gif)
Thanks in advance
Dave
