In this paper, we imitate human bone (arm bones) as structural beam for the analysis. Realistic cross sections of the three human arm bones (radius, ulna and humerus) considered from the real specimens. Bone as complex biological structures is converted into the simple structure which may be analyzed with an ease by existing theory. Modeling of human arm bones and hypotheses used in this paper are purely mathematical and they represent the assumptions of classical and Timoshenko beam theories. Findings of this paper give the realistic strength of the normal human arm bones and assessments of the load that a normal human being can take. Deflection analysis is carried out for various loading conditions such as axial, bending, torsion and shear cases when the cross section is non prismatic and irregular in shapes through the length of the bone.
