Answer 1

Explanation:

Isotropic material means a material having identical values of a property in all directions. Glass and metals are examples of isotropic materials.
Homogeneous material is a material of uniform composition throughout that cannot be mechanically separated into different materials.
Anisotropic material's properties such as Young's Modulus, change with the direction along the object. Common examples of anisotropic materials are wood and composites.
Orthotropic materials have material properties that differ along three mutually-orthogonal twofold axes of rotational symmetry. They are a subset of anisotropic materials because their properties change when measured from different directions. eg: wood
