why is dihedral angle important?
437528
Dihedral angle has important stabilizing effects on flying bodies because it has a strong influence on the dihedral effect. Dihedral effect of an aircraft is a rolling moment resulting from the vehicle having a non-zero angle of sideslip. Increasing the dihedral angle of an aircraft increases the dihedral effect on it.

The angle made by the two legs is called the vertex angle. One of the important properties of isosceles triangles is that their base angles are always congruent. This is called the Base Angles Theorem.

The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation 'd'. As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased.

The calculation of the correct number of degrees of freedom is important because the number of degrees of freedom determines the critical value at which you accept or reject a hypothesis. Thus the degrees of freedom help us to achieve desired confidence level, or the goal, in general in other tests.

The advantage with standard form is that the roots and y-intercept of the parabola can be easily determined and the equation is easily differentiable. The general shape and direction is given by the constant a.

The base and top surface are the same shape and size. It is called a “right” prism because the angles between the base and sides are right angles. A triangular prism has a triangle as its base, a rectangular prism has a rectangle as its base, and a cube is a rectangular prism with all its sides of equal length.

If the diagonals of a parallelogram are equal, then show that it is a rectangular. so ∠ BAD and ∠ CDA are right angles as they are congruent and supplementary.

The term "high symmetry" refers to the fact that at such a local point you have more symmetry elements that copy this point onto itself. You need to distinguish direct and reciprocal space though.

The lone electron pairs exerts a little extra repulsion on the three bonding hydrogen atoms to create a slight compression to a 107o bond angle. The molecule is trigonal pyramid molecular geometry because the lone electron pair, although still exerting its influence, is invisible when looking at molecular geometry.

Atoms, groups, bonds, or other objects lying within the same plane are periplanar or coplanar.

No. For triangles to be similar all 3 sets of corresponding angles must be congruent. In an acute angle all three angles must be acute.

The metal rhodium (Rh) has an FCC crystal structure. If the angle of diffraction for the (311) set of planes occurs at 36. 12∘ (first-order reflection) when monochromatic x-radiation having a wavelength of 0.0711 nm is used, compute the following: (a) The interplanar spacing for this set of planes.

Triangles are the strongest shape because they have fixed angles and don't distort very easily. Michael Busnick, owner of American Ingenuity, which sells dome homes, says triangles are key to making domes strong. ... The pattern of those triangles is critical to the structure of geodesic domes.

If the dot product is negative then the angle is greater than 90 degrees and one vector has a component in the opposite direction of the other. Thus the simple sign of the dot product gives information about the geometric relationship of the two vectors.

A hex bolt relies on a 60 degree angle while the Torx bit relies on a 15 degree angle. The significantly smaller drive angle forms a much tighter tolerance, which better distributes the concentration of force to all points and therefore allows for much higher torque values before rounding out.

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.
