to turn carbon into diamonds, it takes between 237,000 times atmospheric pressure (24 gigapascals) to 1.3 million times atmospheric pressure (136 gigapascals). high pressure and high temperatures in the earth's lower mantle crust are pertinent for the creation of diamonds..how much force is needed to break a cubic meter of stone? - quora,if the stone is softer, you can crush it with a force of 4200 tons or one fourth of the previous figures. crushing rock by brute force is usually not done. a combination of impact and tension is more efficient, specially because most rocks are anisotropic..rock crushing methods and how to recover gold from ores,it just takes a lot of elbow grease and work to break up the rock. a slightly different version of mortar and pestle work is a variety called hand stamp crushing. a heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder..the perfect crush - brew your,the sieves need to travel 18 inches (46 cm) in one direction and then the other, taking 0.5 seconds each way for a total cycle time of one second. every 15 seconds you tap the sieves and pat downward on the working surface. this cycle is maintained for three minutes total.

it turns out that the barrel can withstand about 9 pounds per square inch difference, but beyond that it is simply too much pressure for the metal to withstand and it collapses. because the barrel is round and reinforced with ribs along its outside, it builds up quite a lot of tension and when some imperfection in the roundness occurs, the barrel collapses in a hurry..how much crushed stone do you need? a sure-fire formula,use this formula to determine how much crushed stone you will need for your project: (l'xw'xh') / 27 = cubic yards of crushed stone needed. 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..ask an expert: how much weight is needed to break concrete …,1. concrete is extremely strong in compression mode. if a block of concrete is just sitting on the ground and you try to crush it by putting weights on top, it can withstand tremendous forces. this is why we build skyscrapers out of concrete, or partly why..physics practice problems: work and energy,2. a 2-kg object is being pushed by a horizontal force f along a horizontal frictionless air-table. the object starts from rest at x = 0 and the force f acting on it changes according to the force f v.s. position x graph to the right. a) find the work done by the force
i don’t think it’s quite that strong, but a big lobster can probably do a decent amount of damage if it wanted to. according to this abstract, the maximum force they recorded for a crusher claw from a lobster with a 172 mm carapace was 256 newtons, or 57.6 pounds. by comparison, here’s a list for human bite force, from this article (pdf):.crush and run: the comprehensive guide - braen stone,volume – the first thing that you’ll need to consider is how much crush and run you’ll actually need to complete the work. it should go without saying that the more crush and run required, the more you’ll need to invest. the amount needed will vary depending on.6.5e: exercises on work - mathematics libretexts,18) [t] the force of gravity on a mass m is f = − ((g m m) / x 2) newtons. for a rocket of mass m = 1000 kg, compute the work to lift the rocket from x = 6400 to x = 6500 km. (note: g = 6 × 10 − 17 n m 2 / kg 2 and m = 6 × 10 24 kg.).q: when something falls on your foot, how much force is involved…,this is why padding is so important; if that distance was only an eighth of an inch (seems reasonable) then the force jumps to 4,000lbs, and if that distance is increased to half an inch then the force drops to 1,000 lbs. the bowling ball picture is from here.
