Assignment

Assignment

  • 1.The column is used to support the floor which exerts a force of 3000 N on top of the column. The effect of soil pressure along its side is distributed as shown. Replace this loading by an equivalent resultant force and specify where it acts along the column, measured from the base A.


Assignment1

Assignment

  • 2.The wall footing is used to support the column load of 12,000 N. Determine the intensities w1 and w2 of the distributed loading acting on the base of the footing for equilibrium.
