Kuti uwane kukwirisa kwekutanga, makambani muindasitiri anozosangana nemitengo isingachinji, uye indasitiri yekupa curves haizomira kumusoro. Kana indasitiri ikashandisa huwandu hunonzwisisika hwechinhu ichocho chekugadzira, kuwedzera mukugadzirwa kweiyo indasitiri kucharatidza kuwedzera kwemitengo. Asi chinhu chakadai chinogona kushandiswa munzvimbo dzechigadzirwa cheindasitiri, uye kukwira kwemutengo wechinhu ichocho kuchave nemhedzisiro pane kupihwa kweavo vanotsiva. Naizvozvo, Sraffa akataura, mhedzisiro yekutanga yekushandurwa kwechikumbiro chekutsvaga kweindasitiri yekutanga pasi pezvifungidziro izvi zvinosanganisira shanduko mukutsvaga kwekutsvaga kwekutsvaga kweindiswa kweindasitiri iyoyo, uye zvinotevera shanduko mukutenderera kwekutanga kweindasitiri.
