How to find the mass of a rock

If you have any 2 quantities you can determine the third one. By their very nature many Mass Rock sites are often in out of the way places or situated on private land and it is therefore not possible to visit all the sites recorded.

Uniaxial compressive strength ci of the intact rock pieces value of the Hoek-Brown constant m i for these intact rock pieces and value of the Geological Strength Index GSI for the rock mass.

How to find the mass of a rock. You can measure it different ways. You can use a formula Dmv where D is density m is mass and v is volume. If you have any 2 quantities you can determine the third one.

For example say that you have an idea as to the density of the rock in question but you do not have an instrument to accurately measure its mass. Multiply the volume of the rock by its specific gravity. The resulting number is the weight of the rock.

Keep in mind that this figure will be an approximation if the. Jointed rock masses three properties of the rock mass have to be estimated. Uniaxial compressive strength ci of the intact rock pieces value of the Hoek-Brown constant m i for these intact rock pieces and value of the Geological Strength Index GSI for the rock mass.

A method proposed by the International Society of Rock Mechanics ISRM provides standardized quantitative and qualitative information on rock masses. This and other rock mass classification systems are described in ASTM D5878. To introduce and explain the ISRM method several figures and tables were prepared primarily to provide a standardized definition of terms.

Fig-1 provides an illustration of a rock mass. How to Find the Density of a Rock Sample Selection. Rocks range from a collection of crystals of one mineral to mixtures of different minerals.

The concepts of mass and weight confuse many people. Mass measures the amount of matter in an object. This website is intended as a two way repository to help identify and record the location of Mass Rock sites across the whole island of Ireland.

By their very nature many Mass Rock sites are often in out of the way places or situated on private land and it is therefore not possible to visit all the sites recorded. They come in various colors and often contain glittery mica. Next check the rocks grain size and hardness.

Coarse grains are visible to the naked eye and the minerals can usually be identified without using a magnifier. Fine grains are smaller and usually cannot be identified without using a magnifier. Finding the mass percent requires the molar mass of the elements in the compound in gramsmole or the number of grams used to make a solution.

It is simply calculated using a basic formula dividing the mass of the element or solute by the mass. Which of these is needed to measure the mass of a rock. A A balance B A barometer C A metric ruler D A Thermometer View All Answers 5 Ans 1.

To find the volume of the rock subtract the initial volume of the water from the final volume of the water. 50 mL - 30 mL 20 mL. Therefore the volume of the rock would be equal to 20 mL or 20.

If you take a block of sandstone that is 2 inches by 2 inches and weigh it then take a block of marble that is 2 inches by 2 inches and weigh it you will find that the marble far out weights the sand stone. The rocks general shape. The approximate formula 0335P1 P2 3 Weight of rock W in pounds can be used.

To obtain the equivalent d use this formula. D inches 24 x W⅓. Use the following procedure for the perimeter measurement method.

All you need is a weighing scale and a measuring cup. Pour some water into the measuring cup enough so that the rock can fully drown. Note the level of the water V1.

Put the rock gently into the cup. The volume will increase. If you assume that the rock is a perfect sphere you can measure the diameter of the rock and use the formula.

Vfrac 4 3pi r3 V 34 πr3 with V the volume and r the radius or half the diameter of that sphere. The rock mass is moderately jointed with joints striking perpendicular to the tunnel axis which is being driven east-west and dipping at between 20ｰ and 50ﾂｰ. Table 2 gives the rating for B 24 for driving with dip defined below.
