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

The point within the cross sectional plane of a beam through which the resultant of the external loading on the beam has to pass through to ensure pure bending without twisting of the cross-section of the beam is called

Cross-section of a column consisting of two steel strips, each of thickness t and width b is shown in the figure below. The critical loads of the column with perfect bond and without bond between the strips are P and Po respectively. The ration P/Po is

A steel column, pinned at both ends, has a buckling load of 200kN. If the column is restrained against lateral movement at its mid-height, its buckling load will be
