No, I'm not an instructor, but I do advanced training for licensed pilots, and I've fixed a lot of broken planes. Like people, machines have natural frequencies, and the capacity to accept some forces and loads, but not others. A vital element of people and machine longevity is to understand these natural frequencies and capacities, and operate within them. Cessna nose struts are tough, but can be worn out and broken by misuse.
If you feel the machine, it'll often tell you...
