"Suppose you have a very long steel bar, with a regular pentagonal cross-section where each side of the pentagon is 2 cm in length. This bar will be suspended vertically over a very deep chasm. At the bottom end of the steel bar, there is a spherical steel weight with a diameter of 50 cm. Going up the bar, at every 3 metre increment, there is a spherical steel weight with a diameter of 30cm. If the density of the steel is exactly 7.8 g/cm³, the steel can withstand a tensile stress of 400 MPa, and gravity is 9.81m/s², what is the maximum possible length, in metres, that the bar can extend without breaking?" I just have to ask, is this a legit question? And if so, where the heck did you find It?

I just have to ask, is this a legit question? And if so, where the heck did you find It? Yes - it's legit, and I already posted the answer when asked to do so. Basically, you are being asked to work out how long the bar can be before its own weight causes it to break. It's the sort of question you might expect to find in an advanced physics exam, or structural engineering. But I actually copied and pasted it from a children's game website ;D
