Question

A girl is wearing a pair of flat shoes. She weighs 550 N. The area of contact of one shoe with the ground is 160 cm². What pressure will be exerted by the girl on the ground if she stands on one foot ?

Answer 1

Area = 160 cm² (160/10,000 = 0.016 cm²)
Pressure = ?
Weight = 550 N
`"Pressure" = "Force"/"Area"`
= `550/0.016`
Pressure = 34,375 Pa
Answer: Pressure = 34,375 Pa or N/m².
