Tesla's favorite interview trick (almost everyone gets it wrong) #tesla #mechanicalengineering

This is a tricky interview question asked at Tesla. Can you pass it? Let's figure it out together. You pull a rope from both ends. Where is it going to break? Okay, my brain says the middle. That's where all the tension meets, right? Maximum stress. It snaps right there. That's wrong. The tension in a rope

pulled from both ends is the same everywhere. Every single cross-section carries the exact same load. There's no stress peak in the middle. There's no stress peak anywhere. So, theoretically, it could break anywhere. Every point is equally likely. But, Tesla doesn't just want the textbook answer. They want both the ideal and the real case. In

practice, a rope is never perfect. There's a frayed spot, a knot, a point where the diameter is slightly thinner, or a place where the fibers were damaged. Those are stress concentrations, and that's where the rope will break. In this specific case, it's most likely to break near one of the two ends where the

knots or clamps are. Tesla wants to see if you can think beyond the theoretical ideal situation and into the real world. And the engineer who can do that, that's who Tesla hires.
