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 y ou 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
