Uyazi ukuthi kuyini ukumelana nomthelela?
Isho ukuqina kwento ethile ukumelana namandla amakhulu noma ukushaqeka okusetshenziswa kukho. Kuyinkomba ebalulekile yokuphila kokubalulekile ngaphansi kwezimo ezithile zemvelo namazinga okushisa.
Ngokumelana nomthelela kwephaneli yengilazi, kunedigri ye-IK yokuchaza umthelela wayo wangaphandle wemishini.
Lena ifomula yokubala i-Impact JE=mgh
E - ukumelana nomthelela; Iyunithi J (N*m)
m - isisindo sebhola le-stell; Iyunithi kg
g – amandla adonsela phansi angaguquki; Iyunithi 9.8m/s2
h - ukuphakama lapho ukwehla; Iyunithi m
Okwephaneli yengilazi enogqinsi ≥3mm ingadlula i-IK07 engu-E=2.2J.
Okungukuthi: Ibhola lensimbi elingu-225g lehla lisuka ku-100cm ukuphakama liya endaweni engilazi ngaphandle kokulimala.
Saida Glasskhathalela ngayo yonke imininingwane ecelwa amakhasimende futhi uqhamuke nesixazululo esingcono kakhulu sephrojekthi yakho.
