A penetrometer is also used in longer professional cricket matches, to measure how the pitch is holding up over the course of a multi-day match. British horse racing courses have been required, since 2009, to report the readings obtained using a penetrometer, [ 1 ] on each day of a race meeting.
The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
The Fall cone test, also called the cone penetrometer test or the Vasiljev cone test, is an alternative method to the Casagrande method for measuring the Liquid Limit of a soil sample proposed in 1942 by the Russian researcher Piotr Vasiljev (Russian: Пё́тр Васи́льев) and first mentioned in the Russian standard GOST 5184 from 1949.
The test provides samples for identification purposes and provides a measure of penetration resistance which can be used for geotechnical design purposes. Various local and widely published international correlations that relate blow count, or N-value, to the engineering properties of soils are available for geotechnical engineering purposes.
Another method for measuring the liquid limit is the fall cone test, also called the cone penetrometer test. It is based on the measurement of penetration into the soil of a standardized stainless steel cone of specific apex angle, length and mass.
The Drake Passage, between the southern tip of South America and Antarctic, is infamous as one of the most dangerous journeys on the planet. But why is it so rough – and how can you cross safely?
The goal was to measure the thermal properties of Mars' interior, and thus reveal unique information about the planet's geologic history. [ 4 ] The burrowing mole is a pointed cylinder with a smooth outer surface approximately 35 cm (14 in) in length and 3.5 cm (1.4 in) in diameter.
From Nicole Kidman’s erotic thriller “Babygirl,” to a book of sexual fantasies edited by Gillian Anderson, this was the year the female sex drive took the wheel in popular culture.
