Question

An elephant weighing 40,000 N stands on one foot of area 1000 cm² whereas a girl weighing 400 N is standing on one 'stiletto' heel of area 1 cm².
What pressure is exerted on the ground by the elephant standing on one foot?

Answer 1

Area of elephant’s one foot = 1,000 cm² (1,000/10,000= 0.1m²)
Pressure = ?
Weight of the elephant = 40,000 N
`"Pressure" = "Weight"/"Area"`
= `(40,000)/0.1`
= `4 xx 10^5` Pa
Answer : Pressure exerted by one foot of elephant on the ground = `4 xx 10^5` Pa .
