Explanation / Answer

1) Families of

Wood - Hybrid, Aluminium - Metal ,Concrete - Hybrid, Steel - Metal, Bone - Hybrid.

2) Density of

Wood - 50 to 103 kg/m3, Aluminium - 2700 kg/m3, Concrete - 2400 kg/m3, Steel - 7700 kg/m3, Bone - 985 kg/m3.

3) Modulous of elasticity of

Wood - 12Gpa (1,720,000psi), Aluminium - 69Gpa (10,000,000psi) , Concrete - 30Gpa (4,350,000psi), Steel - 200Gpa (29,000,000 psi), Bone - 20.7Gpa (3,000,000psi)

4) Important Material properties of

Wood - Color and odor, specific gravity, moisture content, grain, shrinkage and swelling, and strength.

Aluminium - Light Weight, Corrosion Resistance,Electrical and Thermal Conductivity, Reflectivity, Ductility, Impermeable and Odourless,Recyclability.

Concrete - Resilience, Compressive strength, Creep, Shrinkage, Coeeficient of thermal expansion.

Steel - Tensile stength, Toughness, Durability, Hardness, Shear strength.

Bone - Strength, Toughness, Density, Colour, Thickness.

5) Generic cost of unit weight of

The cost will general vary depending on many factors like type of material, Grade of material, place of manufacturing of material etc. so it cannot be given a constant value
