Hi all I have a project in which I need to flatten the ends of some 1-1/4 inch SCH 40 (1.66 OD X .140 wall) carbon steel pipe. The flat part needs to be about 4 inches long. My question is how much force will be required to do this? I'm hoping to be able to make a press from a bottle jack to be able to do this but have no idea what size jack will …

It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year. A block 12 inches wide and 24 inches long has a total surface of 288 square inches, or, deducting ⅓ for openings, a net area of 192 inches. Such a block, 9 inches high, weighs 130 ...

5 Dynamic Crush Strength Guideline The speed the impact object hits the honeycomb does have an effect on the honeycomb crush strength. The dynamic crush strengths are greater than the static strengths, and are a function of the honeycomb density and impact velocity. The denser the honeycomb and the faster the impact velocity, the higher the

saplanti 's sheet is what you need. To know the force that will fail the pipe take zero internal pressure and 1.5 times the maximum bending stress equal to yield strength. Note that saplanti 's sheet does not calculate the longitudinal bending stress, and uses an effective length calculating the pipe as if it was that long.

Crushing Strength. Sometimes known as compression strength parallel to the grain, this is a measurement of the wood's maximum crushing strength when weight is applied to the ends of the wood (compression is parallel to the grain).
