The total cross-sectional area of the load-bearing calcied
Chapter 9, Problem 9.12(choose chapter or problem)
The total cross-sectional area of the load-bearing calcied portion of the two forearm bones (radius and ulna) is approximately 2.4 cm2. During a car crash, the forearm is slammed against the dashboard. The arm comes to rest from an initial speed of 80 km/h in 5.0 ms. If the arm has an effective mass of 3.0 kg and bone material can withstand a maximum compressional stress of 16 107 Pa, is the arm likely to withstand the crash?
