1. The problem statement, all variables and given/known data To give a bit of context, I am doing my final year university project on micro-mechanical interactions between an AFM probe and a sample surface. I do not have notes for a system this complicated, as we always considered our systems to be rigid bodies. I was always relatively clueless at mechanics so this particular small part of my project is a nightmare for me! I have labelled the Free Body Diagram attached, but the following information should help to explain further: Section A has a downwards-vertical displacement being applied, and can be considered a rigid body, fixed in all other DOFs. A key feature of this system is the bending cantilever beam (Section B as marked in FBD). It begins with an angle of 13 degrees from the horizontal axis, the inclined beam can be seen on the image FBD. Section C (probe tip) can also be assumed to be a rigid body. Section D is the sample surface which can be assumed rigid and fixed in all DOFs. How do I get to the solution for finding Fz/Fy components and moments on the sample surface from the probe tip? I have not given values for the system because I want to use the help provided to work through it myself. 2. Relevant equations I know there are moments relating to a bending with a stiffness. Not used to a system where a displacement is producing the force vector on the other end of the system. 3. The attempt at a solution As I say, this is a relative nightmare for me and I don't really know where to start, so all help will be greatly appreciated. I'm sure I'll need to provide more information to helpers, so these will be answered in EDITS below.
