  • Estimating Rock Mass Strength - BM 1997 02

    The strength of jointed rock masses is notoriously difficult to assess. Laboratory tests on core samples are not representative of a rock mass of significantly larger volume. On the other hand, in situ strength testing of the rock mass is seldom practically or economically feasible.

    Indirect Shear Test Theory Shear strength is a very important rock property that is used extensively in mine design. Shear along with compressive strength determine what excavations may be made in a rock mass. Shear strength in rock is determined by the imperfections such as joints or foliations present within the rock.

  • MUSCULAR STRENGTH LAB - cstl-hhs.semo.edu

    MUSCULAR STRENGTH LAB Name_____Lab_____ Introduction: Muscular strength refers to the maximum amount of force that an individual can voluntarily generate. Thus, the stronger the individual, the greater the amount of force that can be generated. A widely used operational definition is the one-repetition maximum lift (1RM).
