Parallelograms

The sum (resultant) of vectors A and 5 is a vector C found using the parallelogram law graphically shown as... 

Parallelogram (opposite sides parallel). A = ah = ab sin 6, where a and b denote the sides, h the altitude, and 6 the angle between the sides. 

Rhombus (equilateral parallelogram) A = V2ah where a, h are the lengths of the diagonals. 

Ashton observed that skew (parallelogram-shaped) isotropic plates under uniform distributed load Po as shown in the orthogonal X-Y coordinates in Figure 5-9 are governed by the equilibrium differential equation...

Prisms and pyramids are described by their bases a triangular prism has a triangular base, a parallelpiped is a prism whose base is a parallelogram and a... 

Parallelogram law for the addition offorces. Two forces, and F, acting on a particle may be replaced by a single force, R, called their resultant. If the two forces are represented as the adjacent sides of a parallelogram, the diagonal of the parallelogram will represent the resultant (Figure 2-1).

From fee definition of fee vector product given above, it is clear that fee magnitude of fee vector C in Eq. (22) is equal to the area of the parallelogram defined by fee vectors A and B which describe its sides. However, there are two problems associated wife this definition. First of all, the direction of fee vector C is ambiguous in fee absence of a convention. It is usually assumed, however, feat fee "right-hand rule" applies. Thus, if the first finger of the right...
