Learning Objectives:

• Define:
  • Mechanical Stress
  • Strain
  • Tension (tensile strain and tensile stress)
  • Compression (compressive strain and compressive stress)
  • Shear (shear strain and shear stress)
  • Elastic modulus (Young's Modulus)
  • The various descriptors of mechanical strength: yield, ultimate, and failure strength
  • Stiff, ductile, brittle, and pliant
  • Toughness
• Identify and describe bending and torsion loads
• Describe:
  • The stress patterns that develop under a bending load
  • The general stress-strain relationship for an elastic material
  • Elastic and plastic behavior
• Understand the material properties of bone, tendon and ligament, and muscle
