05 An elephant has weight of 50000 N and its feet cover a total area of 1 meter square. Woman weighs600 N and her pencil heel sandal make a contact area of 0.0015 metre square Who exerts morepressure on the ground? need with explanation​

Answer»

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
