\nAfter I bought a second weight scale, making sure it works accurately, I got home, and noticed I shouldn't have put any bascula on carpet to measure. On a solid ground, both weights measure up to expectation, a 170LBS.\n<\/p>\n
\nIn theory, I gathered that the carpet increased the force upon the weight because it has potential energy in its elastic structure.\n<\/p>\n
\nFor experiment, I'd need two springs, one on top of another and put a weight upon the top, comparing the spring in the middle by observation with another case where there's only one spring involved. Both tests set the springs upon solid surface.\n<\/p>\n
\nNow I end up with 1 extra bascula. I should sell it or else give away for free on craigslist.<\/p>\n","protected":false},"excerpt":{"rendered":"
