The CBR test is a penetration test in which a standard piston, with a diameter of 50 mm (1.969 in), is used to penetrate the soil at a standard rate of 1.25 mm/minute. Although the force increases with the depth of penetration, in most cases, it does not increase as quickly as it does for the standard crushed rock, so the ratio decreases.
It is a pointed cone attached to a spring-loaded handle by extension spindles. The device is pushed into the ground and a scale reads off the estimated CBR value. It is a quick and simple means of estimating the CBR of the top 0.5 metres of subgrade but is less accurate than the more involved standard CBR test.
In this report the CBR-method (California Bearing Ratio) is primarily referred to. The so-called CBR-value represents the ratio of the percentage of the loads required to press a punch of certain dimensions first into a well compacted sample of soil and then into a standard sample of compacted gravels, to a depth of 0.1 inch.

The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]
By 1992, IronMind had moved all design and production of its grippers in-house. [14] The next generation of the Silver Crush Grippers, released in 1993, marked the next major step in gripper evolution; their stainless-steel handles replaced the previous chrome-plated mild steel handles, and a new assembly technique eliminated the drift pin central to the design of the older grippers.

Gravel (largest fragment in this photo is about 40 mm (1.6 in)) Gravel (/ ˈ ɡ r æ v əl /) is a loose aggregation of rock fragments.Gravel occurs naturally on Earth as a result of sedimentary and erosive geological processes; it is also produced in large quantities commercially as crushed stone.
The second part of the episode is noted for the intense performance of Patrick Stewart and its depiction of brutal torture and interrogation scenes. [1] The episode has been frequently ranked among the ten best in The Next Generation. This episode has guest performances by Ronny Cox as Captain Jellico, and David Warner as Gul Madred. [2]
