Question

The discs in the spinal column can withstand a stress (force per unit area) of 1.1 × 107 N/m2 before they rupture. (a) If the cross-sectional area of your discs is 10 cm2, what is the maximum force that can be applied before rupture takes place?

Answer 1

maximum stress that spinal chord can withstand is given as

`stress = 1.1 * 10^7`

now we know that stress is defined as

`stress = (Force)/(Area)`

now here we will have

`Area = 10 cm^2 = 10^(-3) m^2`

now by the above formula we will have

`1.1 * 10^7 = (Force)/(10^(-3))`

now solving for force F

`F = 1.1 * 10^7 * 10^(-3)`

`F = 1.1 * 10^4 N`

so above is the maximum force that it can withstand
