The measurements find whether the soil is strong enough to build a road on. Scientists also use a penetrometer to measure how much moisture is in soil. Penetrometers are used by space probes such as the Cassini–Huygens probe, to measure the amount of moisture in soil on other planets.
The original cone penetrometers involved simple mechanical measurements of the total penetration resistance to pushing a tool with a conical tip into the soil. Different methods were employed to separate the total measured resistance into components generated by the conical tip (the "tip friction") and friction generated by the rod string.

Symbol used in drawings Standard penetration test N values from a surficial aquifer in south Florida.. The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil.
WASHINGTON (AP) — The criminal charges against Hunter Biden “were the culmination of thorough, impartial investigations, not partisan politics,” the prosecutor who led the probes said in a report released Monday that sharply criticized President Joe Biden for having maligned the Justice Department when he pardoned his son.
