Another example is, as a machinist, we tighten the collet chuck nut to different torque specifications depending on the collet holder (tool holder) size. As different torque settings can have different effects on the tool as it spins up to 10,000 rpm (and many even higher). Can cause the tool to be held to tightly and deform the holder, or to loosely and the tool could come out. And if the torque is too high or low it can cause deflection as well (deviation in the center of the tool over a distance).
