Problem when the deformation of a mechanical system is greater or equal to the functional looseness:
left: perspective general view, with a symbolic saw explaining the what a cross section is;
right top: undeformed system, with highlighting of functional looseness (clearance, there is normally only one arrow, but this is a pedagogic drawing for people who don not know technical drawing);
right bottom: the axis is bent and touches the boring at the red points.
