Consider four identical circular Euler columns under a compressive axial load with a) one end fixed and the other pinned (or hinged or simply-supported), b) both ends fixed, c) both ends pinned (or hinged or simply-supported), d) one end fixed and the other free. What are the buckling loads Pcr for each one and which one is the strongest against buckling? Given are: the length L of the column and bending rigidity EI, ?

a member in a braced frame supports an axial compressive load
and end moments that cause bending about both axes of member. A
second order analysis was performed with factored loads and and
reduced members stiffnesses to obtain the moments and axial forces.

A short reinforced concrete column is subjected to a
1000 kN axial compressive load. The moduli of elasticity of plain
concrete and steel are 25 GPa and 207 GPa, respectively, and the
cross-sectional area of steel is 2% of that of the reinforced
concrete. Considering the column as a structural member made of a
composite material and subjected to load parallel to the steel
rebars, calculate the following:

A metallic circular plate with radius r is fixed to a tabletop.
An identical circular plate supported from above by a cable is
fixed in place a distance dd above the first plate. Assume that dd
is much smaller than r. The two plates are attached by wires to a
battery that supplies voltage V.
1) What is the tension in the cable? Neglect the weight of the
plate.

A cantilever of circular solid cross section is fixed at one end
and carries a concentrated load P at the free end. The diameter at
the free end is 200mm and increases uniformly to 400 mm at the
fixed end over a length of 2m. At what distance from the free will
the bending stresses in the cantilever be maximum? Also calculate
the value of the maximum bending stress if the concentrated load
