A bone sample (depth = 8 mm, width = 12 mm, length = 15 mm) failed at 335 N during tensile loading. What are the cross sectional area (CSA) and the ultimate stress for the sample. Note: use the SI units, stated in the table.

Question

CSA is calculated by multiplying depth by width, after converting mm to m (i.e. dividing by 1000). Stress (in Pa) = Force (in N)/CSA (in m²), and then converted by MPa by dividing by 1,000,000.
