Rock Strength Testing | Alliance Geotechnical
When the limit of comprehensive strength is reached, specimens fail and are crushed. The UCS itself is the maximum force that a specimen can withstand before failure occurs. Point Load Test – Used to determine the Point Load Strength Index (Is(50)). This index provides a method for establishing rock strength classification.
Uniaxial Compressive Strength - an overview ...
Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
Unconfined Compressive Strength Test of Rock
This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test Procedure Check the ability of the spherical seat ...

How to Test Muscle Strength for Rock Climbers – …
She introduced me to using a cheap ($10-$18) luggage scale to quantify strength for rock climbers. This was a game changer for me. Since I work with so many climbers remotely, this gave me the ability to monitor muscle strength and track muscle recovery across the globe.
