Shin Ƙididdigar Kuɗi na Lokacin bazara yana ƙarya game da Ƙarfin Ƙarfafawa?
Kun ƙididdige ƙarfin ta amfani da madaidaicin bazara, amma taron ku ya gaza. This mismatch causes delays and questions about your design's reliability, barin ku nemo guntun da ya ɓace.
The spring akai[^1] (Kr) kawai tsinkaya karfi bayan ka rinjayi tashin hankali na farko[^2]. Jimlar ƙarfin faɗaɗawa shine jimlar tashin tashin hankali na farko da ƙarfin da aka ƙididdige shi daga madaidaicin bazara da nisa mai nisa. Yin watsi da tashin hankali na farko yana haifar da tsinkayar karfin da ba daidai ba.
I've seen countless projects get derailed by this exact misunderstanding. Da sauƙi dabarar da muka koya a cikin azuzuwan kimiyyar lissafi babban mafari ne, amma a duniya na al'ada spring masana'antu, it's what the formula leaves out that causes the biggest problems. Wani mai zane ya taɓa gaya mani, "Math yana aiki akan takarda, but the spring doesn't work in the machine." Wannan jimla guda ɗaya ta kama tazara tsakanin ka'ida da gaskiya. Let's look at why your calculations might be off and how to get them right.
