Woman with pencil heel
Pressure=Force/area
- elephant's centre of mass is divided into four as the total force acts at the centre
the force acting on lanf by it's foot=50000/4=12500N
pressure=12500/1=12500N/m^2
- woman has it's centre if mass directly above point of contact of heel with ground
thus force exerted by woman=600N
pressure=600/0.0015=400000N/m^2
