Question: Riddle thingymabob!.!.!.!?
can any one solve this riddle!?!?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!? Round down to the nearest metre, submit only a number (with no additional or extraneous information), and disregard any deformation of the bar or any other forces acting on the bar!. !.!.!.it will get me a ton of extra credit for my math class!.!.pleez help!.!.!.!.!.!.:) thanxWww@Enter-QA@Com
