In Euclidean geometry, a cyclic quadrilateral or inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. This circle is ... more
The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not ... more
A cantilever is a beam anchored at only one end. The beam carries the load to the support where it is forced against by a moment and shear stress. A ... more
Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge ... more
In engineering, deflection is the degree to which a structural element is displaced under a load.
The elastic deflection of a weightless cantilever

Shear stress,is defined as the component of stress coplanar with a material cross section. The average shear stress is force per unit area. Beam shear is ... more
Time-domain reflectometry or TDR is a measurement technique used to determine the characteristics of electrical lines by ... more
