1. A flower vase in the form of a hexagonal prism, is to be filled with 512 cu.in of water. Find the height of the water if the wet portion of the flower vase and its volume are numerically equal.
I am now on third year college with a Civil Eng'g course. I would like to teach and earn money from it.
A structural steel column with Fy = 250 MPa
having an unbraced length of 3m is to carry a total axial load of 1800 kN. Which of the following sections is most economical (lightest ) for the given loads. The comumn is hinged at both ends.
Section A: Area = 13,800mm2 Ix= 293.63 x106mm4Iy= 67.59 x 106mm4
SectionB: Area = 11,550 mm2 Ix=177.04 x 106mm4Iy=39.14x 106mm4
