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 ...
Work done is defined as the energy transferred when a force acts on an object causing it to move. It is calculated as the product of force and displacement in the direction of the force. The unit of work is ...
Elongation is the increase in length of a material when subjected to tensile stress. It is a measure of how much a material stretches under load and is typically expressed as a percentage of the original length. Elongation is crucial ...
Elastic materials can regain their original shape and size after the removal of an applied force. This property allows them to undergo reversible deformation without permanent change. Elasticity is crucial in various applications such as springs and rubber bands where ...
Modulus refers to a measure of a material’s stiffness or resistance to deformation under stress. It quantifies the relationship between stress and strain in elastic materials. Common types include Young’s modulus for tensile stress shear modulus for shear stress and ...
Cross-sectional refers to the shape or area obtained by cutting through an object perpendicular to its longest dimension. It provides insights into the internal structure and characteristics of the material. In engineering and physics cross-sectional analysis is crucial for understanding ...
