This rock breaker is especially used by geologists to clear dust from rocks or fossils. However, all rock breakers are very efficient for a variety of geological explorations. These days, hydraulic breakers are used more than standard breakers. Hydraulic rock breakers deliver higher force and are quite efficient for larger construction projects.

The bulk density (rhob or Pb) of a formation is based on the ratio of a measured interval''s mass to its volume. In general, porosity is inversely related to the density of the rock. The Pb measurement is derived from the electron density of a formation. This measurement is obtained by a logging device that emits gamma rays into the formation.

This tool will calculate the torque generated around an axis by a force applied at right angle to a lever arm of a specified length. Once you have selected the value and units for force and length, two conversion scales will be produced to show a range of torque values calculated for different values of force and length while the other parameter is kept fixed to the input value
