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 bawuti.

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

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 momwe zafotokozedwera mu logo: zokolola / zolimba mphamvu = 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. Wina: 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 ma 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, wina ndi English, woyezera unit makamaka kwa mainchesi (inchi), chimagwiritsidwa ntchito mu United States, Britain ndi zina European ndi A.mayiko aku 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 zokolola mwadzina za bawuti zimafika 400×0.6=240MPa kalasi
Magwiridwe kalasi 10.9 mkulu mphamvu bawuti, zinthu zake pambuyo mankhwala kutentha, akhoza kukwaniritsa:
1. Mphamvu yokhazikika ya bawuti imafika 1000MPa;
2. Mphamvu yopindika ya bawuti ndi 0,9;
3. Mphamvu zokolola mwadzina za bawuti zimafika 1000×0.9=900MPa kalasi
