Question

A box section of length L = 6 m and cross-sectional dimensions of a = 54mm, b = 32 mm has wall thickness t = 3 mm. This box section is used as a part of structure, and it is subject to a load along its longitudinal axis. The K factor for the end conditions of the column is 0.25 . Calculate the buckling load of the column, which is made of a material with an elastic modulus of E = 128 GPa.

Answer #1

For a 8m long column whose cross sectional dimensions are 0.1m x
0.4m, determine the allowable load using a safety factor of 2.5.
The column is welded at both ends. Its yield stress is 250 MPa and
its modulus of elasticity is 210 GPa. using Euler Formula or J. B.
Johnson Formula.

A
6-m long column is made of a steel girder W200x52 (see the section
properties in the last page). It is loaded concentrically through
the centroid of the section. Given that the steel has the elastic
modulus Est = 210 GPa and the yield stress Y = 340 MPa. Determine
the critical load (Euler Buckling Load, Pcr) where the support at
the column ends are fixed-free support

During construction, field tests were conducted to
assess the suitability of the column to withstand a safe buckling
load of 2.5 kN assuming a factor of safety 4 using two different
hollow columns made up of steel and concrete. Both columns have
same cross section but varying length and different support
conditions. Steel column of length 3 m having external diameter 40
mm was tested with one end fixed and the other end hinged, when
subjected to a compressive stress...

A rod has a square cross section of (5 x 5) mm. length of the
rod is 120 cm. The allowable stress is 400 MPa. After applying the
load (F), square section changes to (4.95 x 4.95) mm.
1. What is the type of the load (F), is it tension or
compression?
2. What is the longitudinal strain in steel rod?
3. What is the modulus of elasticity of the material of the
rod?
4. What is the value of...
