12. A lady weighing 500 newtons has shoes with stiletto heels. Each heel has an area of
0.5 cm2. If the lady puts all her weight on one heel, what pressure does she put on
the floor. Would you rather have your toe stepped on by the lady in stiletto heels,
or the elephant, described in the previous question? Why?
Answers
Thrust Or Force Applied By The Ladies Weight = 500 N
Area Of the Heel of the shoe =0.5cm^2
Pressure= Thrust/Area
P= 500/0.5 =1000 N/cm^2 or Pascal.
So pressure exerted on the floor is of about 1000 Pascal.
The average pressure exerted on the ground when being walked over by an elephant is about 54000 Pa.
But If you got stepped on by a stilleto You would get a hole in your body. But being trampled by an elephant will leave nothing in you. If it is just about stepping on a toe I would prefer elephant Or if you consider about being stepped on your body I would then prefer stilleto because a single hole is better than a crushed and dead body.
