Simplifications have used a formula involving the board ECT, the board thickness, and the box perimeter. Most estimations do not relate well to other box orientations, box styles, or to filled boxes. In order to calculate the value of BCT (Box compression test), the formula of McKee would be the easiest but also the least accurate [opinion].
TITAN2D is a free software application developed by the Geophysical Mass Flow Group at the State University of New York (SUNY) at Buffalo. TITAN2D was developed for the purpose of simulating granular flows (primarily geological mass flows such as debris avalanches and landslides) over digital elevation models (DEM)s of natural terrain.
is the half thickness at a given value of x (centerline to surface), t is the maximum thickness as a fraction of the chord (so t gives the last two digits in the NACA 4-digit denomination divided by 100). In this equation, at x = 1 (the trailing edge of the airfoil), the thickness is not quite zero. If a zero-thickness trailing edge is required ...
[1] [2] The point on the leading edge used to define the main chord may be the surface point of minimum radius. [2] For a turbine aerofoil, the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up.
a=chord, b=thickness, thickness-to-chord ratio = b/a The F-104 wing has a very low thickness-to-chord ratio of 3.36%. In aeronautics, the thickness-to-chord ratio, sometimes simply chord ratio or thickness ratio, compares the maximum vertical thickness of a wing to its chord.
A rounded edge would behave as a blunt body in supersonic flight and thus would form a bow shock, which greatly increases wave drag. The airfoils' thickness, camber, and angle of attack are varied to achieve a design that will cause a slight deviation in the direction of the surrounding airflow.

In 1994, Desai challenged engineers at Titan to design the world's thinnest watch, with a movement 1.15mm thick inside a 3.5mm case. [8] The watch, called the Titan Edge was introduced in 2002. [9] After Titan's success, Desai founded Tanishq, a jewelry brand. He had innovative ideas like asking people in Bangalore to get their jewelry ...
