m Review 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. A column is made from a rectangular bar whose cross section is 5.5 cm by 9.1 cm . If the height of the column is 2 m, what is the maximum load it can support? The material has E = 200 GPa and Oy = 250 MPa Express your answer with appropriate units to...

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...

The block diagrams below show states of stress on soil elements.
For each state of stress, perform the following tasks:
1. Sketch a Mohr circle of stress
2. Identify the major and minor principal stresses, σ1 and σ3,
and the maximum shear stress, τmax
3. Compute the mean stress and shear stress invariants, p and q.
Note that p = 1⁄2(σ1+ σ3) and q = σ1-σ3 for two-dimensional stress
conditions where we ignore the intermediate principal stress,
σ2.
4. Identify...
