I bet the answer is Velocity, because the faster you spin a component, the more 'tired' it gets. Am I right, or am I right?

This question is giving me so much stress, I might need a geometry lesson and a spa day afterwards!

Hmm, I'm not so sure about that. Velocity seems like it could be a factor too, especially for high-speed applications. But I guess geometry and material properties are the real heavy hitters here.

I'm pretty sure the correct answer is D) Number of cycles. Fatigue is all about how many times a component can withstand the stress before it fails.

Yeah, the more cycles a component goes through, the more likely it is to fail due to fatigue.

I think you're right, it makes sense that the number of cycles would be a key factor in fatigue resistance.

Wow, this question is really testing our understanding of materials engineering! Temperature, pressure, and number of cycles all play a crucial role in fatigue resistance.
