Can One Use the Dynamic Cone Penetrometer To Predict …
Publication: It is a common question asked by the structural engineer to the geotechnical engineer whether one can determine allowable bearing pressure from a set of Dynamic Cone Penetrometer (DCP) results. This often comes as a shock to the geotechnical engineer as the DCP test wouldn't be applicable in most applications. The DCP was …

3.5: Arc Length and Surface Area
The surface area of a frustum of a cone is. 2π ⋅ length ⋅ average of the two radii R and r. The length is given by L; we use the material just covered by arc length to state that. L ≈ √1 + f ′ (ci)dxi. for some ci in the ith subinterval. The radii are just the function evaluated at the endpoints of the interval. That is,

Turbulent Pressure Fluctuation Coherence Analysis on a Slender Cone …
Pressure fluctuations experienced by high-speed reentry vehicles impart significant loads onto the body, and much remains to be quantified particularly for finite angle of attack when separation occurs on the leeward side. To investigate these angle-of-attack effects, we examine the coherence of pressure fluctuations of a slender seven …

The air pressure on a cone moving at high speeds.—I
When a body moves through air at a uniform speed greater than that of sound, a shock wave is formed which remains fixed relative to the body. This wave is situated on a surface where a very abrupt change in density and velocity occurs. It can be seen as a sharp line in photographs of bullets in flight. In front of this surface the air is stationary, behind it there …
