Respuesta :
Pressure or Stress = Force / Area More than 1000 tons of force is needed to shatter a femur. "Landing from a jump exerts half a ton of force within your femur."
I think you are missing some information here. Were you given the stress value?
P = F/A
170 x 10^6 N/m^2 = F/(0.03 m^2)
F = 5.10 x 10^6 N

The femur bone can withstand of force up to 51000 newtons before breaking.
The femur bone is made of a ceramic material, an anisotropic material, which means that tensive and compressive stresses are different to each other. The maximum compressive force ([tex]F[/tex]), in newtons, is determined by the following formula derived from definition of uniform stress:
[tex]F = \sigma_{C}\cdot A_{e}[/tex] (1)
Where:
- [tex]\sigma_{C}[/tex] - Compressive stress, in pascals.
- [tex]A_{e}[/tex] - Effective area, in square meters.
If we know that [tex]\sigma_{C} = 170\times 10^{6}\,\frac{N}{m}[/tex] and [tex]A_{e} = 3.0\times 10^{-4}\,m^{2}[/tex], then the maximum compressive force is:
[tex]F = \left(170\times 10^{6}\,\frac{N}{m^{2}} \right)\cdot (3.0\times 10^{-4}\,m^{2})[/tex]
[tex]F = 51000\,N[/tex]
The femur bone can withstand of force up to 51000 newtons before breaking.
