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.

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.
