A guy wakes up with a massive hangover and stumbles into the kitchen, where he finds his wife.
“Hey, honey, did you upgrade the bathroom?” he asks.
“Why do you ask?” she replies, curious.
“Well, I opened the bathroom door, the light turned on by itself, and a cool breeze blew right into my face! It was amazing!”
His wife glares at him and says, “So you’re the idiot who pissed in the fridge last night!”
Johan August BrinellDied 17 Nov 1925 at age 75 (born 21 Nov 1849).Swedish metallurgist who devised the Brinell hardness test, a rapid, nondestructive means of determining the hardness of metals. Brinell studied many aspects of iron and its production. Brinell´s important work on transformations in steel during heating and cooling. His discoveries about the control of the carbon containing phases is the present basis for the knowledge about properties of steel. The Brinell Hardness Test measures the relative hardness of metals and alloys, by forcing a 10mm hard steel ball into a test piece with a 3000kg load for 30 seconds and measuring the surface area of the resulting indentation. The load is reduced to 500kg for very soft materials and the steel ball is replaced with tungsten carbide for very hard materials. |
