The later ASW-15B had several improvements, including a tow-release placed on the plane of symmetry, an 11 cm taller rudder, a slightly larger main wheel, and the provision of a 90-litre water ballast system.

Under the non-classical description of the 2-norbornyl cation, the plane of symmetry present ( running through carbons 4, 5, and 6 ) allow equal access to both enantiomers of the product, resulting in the observed racemic mixture.

Hannes Alfv�n and Per Carlqvist speculate on the existence of a galactic current sheet, a counterpart of the heliospheric current sheet, with an estimated galactic current of 10 17 to 10 19 amperes, that might flow in the plane of symmetry of the galaxy.

Projecting the self-intersecting disk onto the plane of symmetry ( " z " = 0 in the parametrization given earlier ) which passes only through the double points, the result is an ordinary disk which repeats itself ( doubles up on itself ).
35.
Note that position 6 in quercitol has no-OH ( the only difference from inositol ), which establishes the plane of symmetry : when 3, 24, or 234 are the odd groups out, the result is a mirror plane and hence no optical activity.

Refined calculations by Obata and Hirao ( 1993 ) predict that the most stable form has three orthogonal planes of symmetry ( C 2 " v " ) with the two subgroups in the eclipsed configuration ( unlike ethane, whose ground state has the staggered configuration ).
37.
Dissecting a Klein bottle into halves along its plane of symmetry results in two mirror image M�bius strips, i . e . one with a left-handed half-twist and the other with a right-handed half-twist ( one of these is pictured on the right ).
38.
For example, two hydrogen atoms adjacent to the carbonyl group in " cis "-2, 6-dimethylcyclohexanone are enantiotopic; they are related by an internal plane of symmetry passing through the carbonyl group, but deprotonation on one side of the carbonyl group or on the other will generate compounds which are enantiomers.
39.
If an elastic bar with uniform and symmetric cross-section is bent in one of its planes of symmetry, the resulting "'bending stress "'will still be normal ( perpendicular to the cross-section ), but will vary over the cross section : the outer part will be under tensile stress, while the inner part will be compressed.

If considering'coin dropping'and nor coin flipping ( the coin is not allowed to rotate ) then the probaility of it landing on the'edge'will be the solid angle subtended by the edge divided by the total solid angle ( 4pi ), the angle the rim makes to the plane of symmetry of the coin is a = arctan ( h / 2r ),
