Mathematics. one of a set of formulas for finding the curvature and torsion of a plane or space curve in terms of vectors tangent or normal to the curve.Discover More Word History and Origins Origin of Frenet formula1 Named after their discoverer, Jean (or Frédéric) Frenet (1816–1900),...
A simple and exact formula for the breadth of Debye Scherrer lines is derived, with the assumption that the crystals have the same form and volume. This formula is used to evaluate the integral breadth as a function of the direction of the normal on the reflecting plane for some triclinic ...
Plane strain fracture tests provide additional important data. Following Bridgman 's stress analysis inside the necking of a plane strain specimen, a closed-form solution is derived for the stress triaxiality inside the notch of a flat-grooved plane strain specimen. The newly derived formula is ...

Normal Force Formula | Normal force is the support force exerted upon an object that is in contact with another stable object.
Clearly, from this definition, thevector spacefor a cross product is three-dimensional space. If, for example, the two given vectors in the cross product are both in thexyplane, the resulting vector is perpendicular to these two vectors, and this means a vector that is parallel to thez-...
For a normal current T∈ NmRn, a Lipschitz function u: Rn→ R, and a real number r, define the slice (1)〈T,u,r+〉≡(∂T)∟{x:u(x)>r}−∂(T∟{x:u(x)>r})=∂(T∟{x:u(x)≤r})−(∂T)∟{x:u(x)≤r}. (See Figure 4.11.1 on page 54.) It follows th...
1. The angle of incidence equals the angle of reflection 2. The incident ray, the normal and the reflected ray are all the in the same plane 3. The incident ray and reflected ray are on different sides of the normal. What is meant by reflection of light? The reflection of ...
