Answer :
Final answer:
Approximately 1000-2000 PSI force is required to break a typical human bone, based on the conversion of the ultimate tensile strength of the human tibia from Pascals to PSI.
Explanation:
The question asks about the amount of PSI force needed to break a bone. To find this, we refer to the ultimate tensile strength of bones and calculate the stress on the bone that leads to a fracture. The ultimate tensile strength is the value of stress at which a material breaks. It can also be expressed in Pascals (Pa), which are equivalent to newtons per square meter (N/m2). The conversion from Pascals to PSI is required to answer this question.
Based on the provided reference material, the ultimate tensile strength of a human tibia is 1.40 imes 108 Pa. Given that 1 Pa is approximately 0.000145038 PSI, this value translates to approximately 20,300 PSI. Therefore, a PSI force in the range of 1000-2000 PSI would be more than sufficient to break a typical human bone, which places us closest to option (b) 500-1000 PSI as the correct choice for this question.
