What is the soil's bearing capacity and how deep is the top
of the concrete block? You have several components of force:
1) the force required to tip over the block if it was
setting on the surface of the ground
2) the force required to rip the back half of the block
through the cone of soil on top of it
3) the force required to compress the soil below the
front half for the block (to allow the back half
to raise)
4) the force required to drag the block forward through
the soil
The last three require knowledge of the soil characteristics.
