# Questions & Answers of Shear centre

Consider two axially loaded columns, namely, 1 and 2, made of a linear elastic material with Yong's moduls 2×105 MPa, square cross-section with side 10 mm, and length 1 m. For coloumn 1 one end is fixed and is free Column 2, one end is fixed and the other end is pinned. Based on the Euler's theory the ratio (up to one decimal place) of the buckling load of column 2 to the buckling load of column 1 is _______________

The possible location of shear centre of the channel section, shown below, is

The ratio of the theoretical critical buckling load for a column with fixed ends to that of another column with the same dimensions and material, but with pinned ends, is equal to
