Determining Proper Anchor Length Williams FormGeology at Cone Crater NASA

The pullout capacity of the cone is a function of the weight of the cone and the shear resistance of the rock along the surface of the cone Rock anchors are typically designed with embedments deep enough to ensure ductile failure of the steel bar Mathematically by setting the anchors ultimate steel capacity equal to the pull out capacity of the rock failure cone and applying necessary Geology at Cone Crater By collecting samples from the large rocks near the rim they are certain of giving the geologists back home a look at material dug out by the impact from the deepest part of the crater One use of the samples is to estimate the age of Cone Crater Rock that had been buried deep within Cone Ridge were not exposed to cosmic rays until dug out by the impact and it is
