Kupatsanura: yakaderera coefficient yekuwedzera kwemafuta

Mashandisirwo: Invar inoshandiswa panodiwa kugadzikana kwepamusoro-soro, zvakaita sezviridzwa zvakarurama, wachi, kukwira kwepasi
magauge, mafuremu emumvuri weterevhizheni, mavharuvhu ari mumota, uye mawachi ekudzivirira magineti. Mukuongorora nyika, kana paine odha yekutanga
(high-precision) elevation leveling inofanira kuitwa, tsvimbo dze leveling dzinoshandiswa dzakagadzirwa neInvar, pachinzvimbo chehuni, fiberglass, kana
dzimwe simbi. MaInvar struts aishandiswa mune mamwe mapiston kuderedza kuwedzera kwekupisa mukati memasirinda avo.
