Answer
Ubujyakuzimu bwa $ d $ ni ikintu gikomeye. Byasobanuwe nka $ d = \ frac {D_ {shaft} - D_ {groove}} {2} $ (kuri shafts) cyangwa $ d = \ frac {D_ {groove} - D_ {bore}} {2} $ (kuri bores). Ihagarikwa ryimpeta riterwa n '' ijanisha ry 'ijanisha', nicyo kigereranyo cyurukuta rwa radiyo $ b $ yicaye imbere muri ruhago. Umuyoboro wimbitse wongera ubushobozi bwo gusunika ariko bigatuma kwishyiriraho bigorana kandi byongera ibyago byo 'guhangayikishwa cyane' impeta mugihe cyo guterana. Ubujyakuzimu bwiza $ d $ bwemeza ko no muburyo bwo kwihanganira ntarengwa (ibintu bibi cyane), impeta ikomeza byibuze $ 50 \% $. Kubikoresho byubuvuzi byuzuye, $ d $ akenshi abikwa ntoya kugirango agabanye ikirenge, bisaba ko hakoreshwa impeta ya Beryllium Umuringa kugirango ugumane imbaraga nyinshi zamasoko mugihe gito.
