A Chomby was walking down a path one day when Jhudora appeared in front of it. "Solve this puzzle, and you may pass," she said.

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/cm

^{3}, the steel can withstand a tensile stress of 400 MPa, and gravity is 9.81m/s

^{2},

**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.
