maximum stress that spinal chord can withstand is given as
[tex]stress = 1.1 \times 10^7[/tex]
now we know that stress is defined as
[tex]stress = \frac{Force}{Area}[/tex]
now here we will have
[tex]Area = 10 cm^2 = 10^{-3} m^2[/tex]
now by the above formula we will have
[tex]1.1 \times 10^7 = \frac{Force}{10^{-3}}[/tex]
now solving for force F
[tex]F = 1.1 \times 10^7 \times 10^{-3}[/tex]
[tex]F = 1.1 \times 10^4 N[/tex]
so above is the maximum force that it can withstand
