A uniform steel beam has a mass of 1178kg. On it is resting half of an identical beam, as shown in the figure attached. What is the vertical support at the right end. How about at the left end?
The following wikipedia page is a good reference for this problem:
Essentially, at equilibrium the moments and the forces must add to zero I am including a diagram to explain this a bit better for your problem.
Let SL and SR be the supporting forces the fulcrum for the rotation is the ...
The solution provides a written explanation of how to find the vertical support for a bar resting on another bar, as described, in the answer space as well as attaching the full explanations in a pdf document complete with explanatory diagrams
