Answer:

No it is not a problem

Explanation:

It is not a problem because the stress intensity factor K would approach infinity as you get close to a crack tip and the intensity factor would approach Zero as you get too far away from the crack tip and this is simply because a crack is a notch with zero tip radius .

and The application of stress intensity factor k in respect to present fatigue crack tip is termed " linear elastic fracture mechanics "

<h3>What is a Machine gun ?</h3>

The term "machine gun" refers to a rifled, autoloading, fully automatic weapon intended for continuous direct fire using rifle rounds. Other automatic weapons, such as automatic rifles, are often intended to fire in brief bursts rather than continuously, and are not regarded as real machine guns because of this.

  • Machine guns and other automatic weapons vary in that they fire rounds continually until the shooter lets off of the trigger after pulling it once. Fully automatic guns are uncommon compared to semi-automatic rifles.
