Some complex. Some straightforward like understanding shear. For example,when you mount a bolt in double shear, it is literally supported on both ends,cutting the shear forces in halflike the example inside the red circle here. When you mount a bolt in single shear, like the blue circle, we are putting allthe shear forces trying to bend, break or shear the bolt off. Thats OK if wehave a strong enough bolt.
