Mlingo wakuchita kwa bolt

Bawuti ntchito kalasi, ndicho bawuti ntchito kalasi kwa zitsulo kapangidwe kugwirizana, lagawidwa m'makalasi oposa 10, monga 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc.Bolt ntchito kalasi chizindikiro tichipeza magawo awiri, omwe motsatana amayimira mphamvu yamakomedwe odziwika bwino komanso mphamvu yopindika ya zinthu za bawuti.

Tanthauzo la kalasi ya bawuti ndi muyezo wapadziko lonse lapansi, bawuti ya kalasi yofananira yochita, mosasamala kanthu za kusiyana kwa zinthu zake ndi chiyambi, magwiridwe ake ndi ofanana, kapangidwe kake kakhoza kusankha kalasi yantchito.

Mphamvu ya giredi 8.8 ndi 10.9 magnitude imatanthawuza kuchuluka kwa kumeta ubweya wa bawuti ndi 8.8 GPa ndi 10.9 GPa 8.8 mphamvu yokhazikika ya 800 n / 640 n inali zokolola mwadzina ma bolts / anali ambiri amawonetsedwa mu "XY" mphamvu, X * 100 = mphamvu ya bawuti yamakomedwe, X * 100 * (Y / 10) = mphamvu zokolola za bawuti (monga zafotokozedwera mu logo: zokolola / mphamvu zolimba = Y / 10, zomwe ndi 0. Y adawonetsa) monga kukula kwa 4.8, mphamvu yamagetsi ya bawuti ndi: 400 mpa. Mphamvu zokolola: 400 * 8/10 = 320MPa. Zina: zitsulo zosapanga dzimbiri zosapanga dzimbiri nthawi zambiri zimatchedwa A4-70, maonekedwe a A2-70, kutanthauza kuti fotokozerani miyeso: kutalika kwake. Padziko lapansi lero pali mitundu iwiri ikuluikulu, imodzi ya metric system, gawo loyezera ndi mita (m), masentimita (cm), mamilimita (mm), etc., ku Ulaya, China ndi Japan ndi kumwera chakum'mawa kwa Asia ntchito ndi zambiri, china ndi Chingerezi, gawo loyezera limagwiritsidwa ntchito makamaka ku United States, Britain ndi mayiko ena a ku Ulaya ndi America.1. Muyezo wa dongosolo la metric: 1m =100 cm=1000 mm2, muyeso wa dongosolo la Chingerezi: (8) 1 inchi = 8 inchi 1 = 25.4 mm

Maboti omwe amagwiritsidwa ntchito polumikizana ndi zitsulo amakhala ndi magiredi oposa 10, kuphatikiza 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 ndi 12.9. chiŵerengero cha mphamvu zopindika za bawuti.Mwachitsanzo: mabawuti okhala ndi mlingo wa 4.6, kutanthauza:
1. Mphamvu yokhazikika ya bawuti imafika 400MPa;
2. Mphamvu yopindika ya bawuti ndi 0,6;
3. Mphamvu yotulutsa mwadzina ya bawuti imafika 400×0.6=240MPa kalasi
Magwiridwe kalasi 10.9 mkulu mphamvu bawuti, zinthu zake pambuyo mankhwala kutentha, angathe kukwaniritsa:
1. Mphamvu yokhazikika ya bawuti imafika 1000MPa;
2. Mphamvu yopindika ya bawuti ndi 0,9;
3. Mphamvu yotulutsa mwadzina ya bawuti imafika 1000×0.9=900MPa kalasi
