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?

Respuesta :

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
