Uyazi ukuthi kuyini ukumelana nokushayisana?
Kubhekisela ekuqineni kwezinto ukuze zikwazi ukumelana namandla amakhulu noma ukushaqeka okusetshenziswa kuzo. Kuyisibonakaliso esibalulekile sempilo yezinto ngaphansi kwezimo ezithile zemvelo kanye namazinga okushisa.
Ngokuphikisana komthelela wephaneli yengilazi, kunezinga le-IK lokuchaza imithelela yayo yangaphandle yemishini.
Lena ifomula yokubala ukuthi umthelela J uyiniE=mgh
E – ukumelana nomthelela; Iyunithi J (N*m)
m – isisindo sebhola le-stell; Iyunithi kg
g – ukungaguquguquki kokusheshisa amandla adonsela phansi; Iyunithi 9.8m/s2
h – ukuphakama lapho kwehla; Iyunithi m
Kwiphaneli yengilazi enobukhulu obungu-≥3mm ingadlula i-IK07 okungu-E=2.2J.
Okusho ukuthi: ukuphonsa ibhola lensimbi elingu-225g kusuka ekuphakameni okungu-100cm kuya ebusweni bengilazi ngaphandle komonakalo.
Ingilazi kaSaidakhathalela yonke imininingwane ecelwa amakhasimende bese uthola ikhambi elingcono kakhulu lephrojekthi yakho.
