How would I analize a bolt in tension and shear. Imagine an "L" bracket bolted in the configuration below "||" represents a bolt. There is a force "<--" at the top of the bracket. <--| .....| .....|_____||_ The bolt will see tension and shear. There will be tension in the y direction (Sigma y) and shear on the yx plane (Tau yx). The force in the x direction should be zero and the Shear in the xy plane should be zero. This means the points on the x surface would be (0,0) and the points on the y face woudl be (tension, shear). These points seem to be invallid because the mohr's circle center will not fall on the horizontal axis. What am I doing wrong?
