Squamous epithelial tissue covers surfaces subjected to medhcanical or chemical stress. Examples are the skin, mouth lining, and vaginal lining.

Flakes of bricks primarily result from mechanical processes rather than chemical ones. This occurs when bricks are subjected to stress, wear, or impact, causing them to chip or break apart. While chemical weathering can affect bricks over time, the formation of flakes is typically associated with physical forces.
Photoelastic materials are transparent materials that change their optical properties when subjected to mechanical stress. When stress is applied, these materials exhibit a birefringence effect, which causes them to change colors or patterns under polarized light. They are commonly used in stress analysis and to visualize stress distributions in mechanical components.

The relationship between stress and strain in materials under mechanical deformation is described by Hooke's Law, which states that stress is directly proportional to strain. This means that as a material is subjected to a force (stress), it will deform (strain) in a predictable and linear manner. The relationship between stress and strain helps engineers and scientists understand how materials behave under different conditions and can be used to predict their mechanical properties.
The relationship between stress and strain determines how materials respond to mechanical forces. Stress is the force applied to a material, while strain is the resulting deformation. When a material is subjected to stress, it deforms or changes shape, which is known as strain. The behavior of materials under mechanical loading is influenced by how they respond to stress and strain. Materials can exhibit different properties such as elasticity, plasticity, and brittleness based on their stress-strain relationship.
Sound can be turned into mechanical energy through a device called a transducer. Transducers convert sound waves into mechanical vibrations by utilizing the piezoelectric effect, where certain materials produce an electrical charge when subjected to mechanical stress. This electrical charge can then be harnessed to generate mechanical movement or energy.
Piezoelectric crystals exhibit the property of converting mechanical stress into electrical voltage and vice versa. They are crystalline materials that have a non-centrosymmetric structure, meaning their positive and negative charges are not symmetrically distributed within the crystal lattice. When subjected to mechanical stress, piezoelectric crystals generate a voltage potential across their surfaces, making them useful in sensors, actuators, and transducers.
An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.
