Homework Answers
The given coulmn may fail due to bucking or compression or
compression.
As column is long so buckling failure will occur well before
compression failure.
Hence the column will fail by both bending as well as bucking stress.
Add Answer to:
The column total critical stress may include M y x 16 ft M P O both...

Determine the critical load, Per, required to cause failure of a 21 ft long column made of A-36 structural steel with a moment of inertia of 2.19 in* about the y-y axis, 16.4 in about the x-x axis, and a cross sectional area of A = 2.68 in2. Assume that the column behaves as if it is fixed at its base, and fixed at the top. Be sure to check both buckling possibilities, and the crushing failure mode when determining...

Ideal Column with Pin Supports Learning Goal: To use the formula for the critical load, i.e., the Euler buckling load, for pin-supported columns to calculate various parameters of columns. Ideally, a column that is perfectly straight and has an axial load applied exactly at the centroid of its cross section will not yield until the internal normal stress reaches the yield stress of the material. Real-world columns, however, are subject to small asymmetries, whether due to irregularities of shape or...

3) (40 pts) The EXTERNAL 35 kN force P is applied to the end of a 2 m long cantilever beam with the given cross section. The force acts through the shear center, forming an angle of 35 with the horizontal axis. The x, y axes pass through the centroid C. The y-axis can be assumed to coincide with the right- hand edge of the vertical section. Determine (a) the normal bending stress at Point A, (b) normal bending stress...
