1. Determine the critical buckling stress (for) of a 4" x 4" column. The column is 12' high, pinned at the top and bottom, and the material has a modulus of elasticity of 1.4x100 psi.

Step 3- How did you calculate I (moment of inertia) Can you detail your divisions and multiplications?  Thanks

what is motion? Please explain in details.

The picture shows a maglight, a cardboard square with a square hole in the middle, and a wall. Draw side - view and top - view diagrams showing how the light travels to the wall and a front - view diagram showing the pattern formed on the wall. Use words to help explain the pattern on the wall. Side View Wall Front View (wall) Square Wall Square Top View
