The length / thickness ratio in all of these must be above 1 : 1.5, so that the tiles can steadily stand upright, since Chinese players use no racks to support their tiles in hand during play.

As on the 1926 DB-10, the centre section of the wing of the DB-70 was extremely thick and twice the chord of the outer wings, with a chord / thickness ratio of about 25 %.

During times of high sea-level ( transgressive phases = slight bottom currents ) Sowerbyceras faunas decreased in numbers, and were smaller, with a lower thickness ratio Wb / D ( whorl breadth / Diameter ) and a more evolute conch.

Here the subscript of R denote collinear and oppositely oriented magnetization in layers, " ? = b / a " is the thickness ratio of the magnetic and non-magnetic layers, and ? N is the resistivity of non-magnetic metal.

Rectangular duct section properties are calculated from the distance between the upper to lower duct corners of the ductwork The flanges areas are based on the size of corner angles plus duct plate width based on the plate thickness ratio of 16 * t . ( see AISC structural duct design below ) For section properties the " web " plate is ignored.

However, unlike balsa gliders, paper gliders have a far higher strength-to-thickness ratio a sheet of office-quality 80 g / sq m photocopier / laser printer paper, for example, has approximate in-scale strength of aircraft-grade aluminium sheet metal, while card stock approximates the properties of steel at the scale of paper model aircraft.

The "'plane wave expansion "'method can be used to calculate the band structure using an DBR ) with air-core interleaved with a dielectric material of relative permittivity 12.25, and a lattice period to air-core thickness ratio ( d / a ) of 0.8, is solved using 101 planewaves over the first irreducible Brillouin zone.
