Answers are d=16mm, h=10mm
I tried using methods used in previous questions but it didn't work out for me here, if anyone could give a hand, would be greatly appreciated.
I would also like to clarify a couple of other things related to the theory that I'm not sure about.
- I'm not sure what the relationship is between normal force (P) and shear force (V), particularly if given a normal force (P) for example and the question asks to find shear stress. Would Shear force (V) = P/2. I have basically used this principle and it has been generally successful but I am not sure if I'm getting answers correct because double shear applies.
-Secondly, I was doing a question that involved a couple of beams that had pin-joints on each side. Subsequently, I found the external force applied on each pin joint. I have attached a file and drawn an arrow on the diagram. I would like to verify if the arrow acting on the member is a normal force. Because that's what I assumed and when solving the normal stress it gave me the correct answer. The attachment of the problem is below
