To break its thickest area and back, 1,100 pounds of pressure will be required, and if 520 pounds of pressure is applied to the skull, then the frontal bone of the skull will break because the human skull is very powerful. Factors like the location of the impact and bone density affect the amount of pressure needed.

Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and …

Some individuals with exceptional grip strength have been able to crush an egg with as little as 20 pounds of pressure, while others may need up to 40 pounds. The key factors that determine the amount of grip strength needed to crush an egg include the size and strength of the individual's hand and the technique used to apply pressure.

In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This number is how many cubic yards of crushed stone you need. As an example, let's say your DIY project is a patio, and it calls for the use of crushed st…

Divide the number of cubic feet by 27 to find the number of cubic yards needed. In this case, 84/27 = 3.11 cubic yards of gravel or about 4.5 tons should do the trick. Let's look at several examples to get an idea of how much gravel each shed foundation will need. We'll assume each shed foundation is 6" deep with gravel.

According to equation (17) the strength ratio Fc/Ft (or Co/To) depends on the value of m only. For limestone m=5.4 and Co/To=5.6; for granite m=29.2 and Co/To=29.2; for sandstone m=14.3 and Co/To=14.3. The Hoek and Brown criterion for intact rock can also be expressed in terms of normal and shear stresses as follows.
