Poisson’s ratio is the ratio of the lateral strain to the longitudinal strain when a material is subjected to stress. It is a measure of the material’s ability to deform in one direction when stretched or compressed in another. The ...

Deforming refers to the change in shape or size of an object due to applied forces or stresses. This can occur elastically where the object returns to its original shape or plastically where it undergoes permanent changes. Deformation is a ...
Bulk strain is the change in volume of a material when subjected to uniform pressure. It is the ratio of the change in volume to the original volume. Bulk strain is dimensionless and significant in studying material behavior under compressive ...
Magnitude refers to the size or quantity of a physical property often expressed in numerical terms. It can apply to various measurements such as force mass or energy. Understanding magnitude is essential in physics and engineering as it helps quantify ...
Tension is the force exerted along a stretched object like a rope string or cable when it is pulled from opposite ends. It acts to restore the object to its original length and is directed along its length. Tension plays ...
Load refers to the external force or combination of forces applied to an object or structure. It can cause deformation or motion depending on the type and magnitude of the load. Loads are classified as static dynamic or impact and ...
A unit is a standard measure used to express physical quantities like length mass and time. It provides a reference for consistency in measurements. Units are classified into fundamental and derived types and systems like SI ensure global uniformity. Accurate ...
Liquid crystals are materials that exhibit properties between solids and liquids. They flow like liquids but have an ordered molecular structure similar to solids. Used in displays, sensors, and optical devices, liquid crystals change orientation in response to electric fields, ...
Forces are interactions that cause an object to accelerate, change direction, or deform. They can be classified as contact forces (e.g., friction, tension) and non-contact forces (e.g., gravity, magnetism). Forces are measured in newtons (N) and are described by Newton’s ...
