hypothetically, what would happen if a hydraulic cylinder was bent (that being the cylinder or the rod)? how long till u would know there was a problem? and also, how do technicians check for this during their annual inspections of the hydraulic cylinder?

A hydraulic cylinder can get bent, generally not the fault of the elevator. It is easy enough to identify by a scraping noise that you will hear and feel. This scraping comes from within the cylinder that the hydraulic piston operates. The tolerance is very low inside the cylinder thus a slightly bent cylinder will tell on itself. This same scenario can happen if the piston falls away from the cab and repicks out of plumb.
Hope this helps in your understanding of elevators.
