Kinda, but even better. A sharp edge puts all the stess at the corner, the smaller the actual corner, the more concentrated the stresses become.

      Best example I can think of off the top of my head is one sheet of paper is easy to tear from the edge. But if you try to rip it in half from the middle, it's a lot harder. You have spread the force from your hands over a lot more paper.

      You're dealing with tensile strengths in the crank example. Tensile is the amount of force required to pull a material apart. It's expressed in pounds per square inch. The more square inches presented to the force, the stronger the pull required. It's a bit more complicated than that in a crankshaft, but that's the idea.
