e $3$: The initial footing design for the structures shown in Fig. $1.$You need to calculate the pressure distribution under the initial footing design in Fig. $3($foundation pressure$)$ due to the given column loads in Fig. $1$ and Fig. $2.$ This part basically involves

only statics calculations. To calculate the foundation pressures, you need to:

$1.$ Find the centroids of the given footing

$2.$ Find the resultant forces and moments at this centroid

$3.$ Calculate the pressure distribution based on the resultant forces

Many other calculations in this project depend on the results of this task. Grid dimensions are in $m.$ The table on the

right shows the column loads.

maximum and minimum pressures under

whether the design is acceptable or not
