Not illustrated. 1895 Excerpt: ...strengths of these four classes are as follows: These figures, however, refer to small specimens such as can be used in a testing machine, and it is known that the strength of large blocks per square inch is materially less. The rupture of a cube or prism of stone under compression often occurs by splitting, or rather shearing, in planes making an angle of about 45 degrees with the direction of the pressure (see Fig. 3, Art. 8). In order to insure a perfect distribution of pressure over the surfaces, cushions of wood, leather, and lead are often placed upon them, but the advantage of using them is doubtful. The coefficient of elasticity of stone has been found to range from 5 000000 to 10000000 pounds per square inch. The elastic limit is difficult to observe, if indeed any exists. Little is known of the tensile and shearing strengths of stone, except that they are smaller than the compressive strength in some varieties. Tests to determine the modulus of rupture by loading a stone beam to destruction are easily made, and will probably serve to compare the quality of different specimens better than other tests of strength. Slate is an argillaceous stone consolidated under very heavy pressure so as to form a marked cleavage at right angles to the direction of that pressure. It is split into plates inch in thickness for use as roofing slate, and in larger blocks is used for pavements and steps. Its weight per cubic foot is about 175 pounds, its compressive strength about 10000 pounds per square inch, and its modulus of rupture about 7 000 pounds per square inch. Unfortunately it is liable to corrode under the action of the atmosphere, and its marked cleavage and grain render its strength variable in different directions.
