The purpose of this experiment is to use a three-point bending test to determine the failure properties of chicken bones without marrow. The failure properties of chicken bones with marrow and without marrow will be compared.

Chicken bones without marrow resemble hollow rods with cylindrical cross sectional areas. It is hypothesized these bones would therefore produce more uniform fracture patterns that more closely resemble fracture patterns of beams than chicken bones with marrow. Additionally, it is hypothesized that bone specimens without marrow will exhibit significantly weaker structural properties that the bones with marrow. Based on research¹, a 0.11% reduction in maximum force and a 0.44% reduction in stiffness are hypothesized to occur in the mechanical properties of chicken bones without marrow in comparison with chicken bones with marrow.
