Ok... I feel so incredibly stupid for asking this, but I as well as my electrical engineer are stumped.
I am working on an issue regarding side loading in compression springs, and I am analyzing the data our instron tester is giving us. From this data I will be able to tell at what position in 3D space the test force is occuring and translate it back to a side load and moment. However, I for some reason am getting answers that do not make sense.
Ok... Here is the problem...
I have three positions of the spring, top side P1, bottom side P2, and test height P3. I have the (x,y,z) coordinates for P1 and P2 but only the z for P3. P3 is on the same line as P1 and P2....
so correct me if I am wrong in this assumption....
Vector A: (P1x-P2x)i + (P1y-P2y)j + (P1z-P2z)k
Vector B: (P3x-P2x)i + (P3y-P2y)j + (P3z-P2z)k
Vector C: (P1x-P3x)i + (P1y-P3y)j + (P1z-P3z)k
Vector A = Vector B + Vector C Is this not correct?
The problem is P3x and P3y are un known and I need to solve for them, but in the above equations they end up cancelling out as thogh they are zero... I don't know, perhaps I am over analyzing this... can anyone provide insight? I can give actual data if needed.... Thanks
