Uyazi ukuthi yini ukumelana nomthelela?
Kubhekisa ekunciphiseni kokuqina kokumelana namandla amakhulu noma ukuthumba okusetshenzisiwe kukho. Kuyinkomba yokungafanele impilo yento engaphansi kwezimo ezithile zemvelo kanye namazinga okushisa.
Ngomthelela wokuphikiswa kwephaneli yengilazi, kune-IK degree ukuchaza imithelela yayo yangaphandle yemishini.
Le formula ukubala umthelela JE = mgh
E - ukumelana nomthelela; Unit j (n * m)
m - isisindo se-stell ibhola; Unit kg
g - ukusheshisa amandla adonsela phansi; Unit 9.8m / s2
h - ukuphakama lapho kwehla; Unit m
Iphaneli yengilazi enobukhulu obukhulu ≥3mm ingadlula ik07 okuyi-e = 2.2J.
Lokho wukuthi: 225g ibhola lensimbi yehla kusuka ekuphakameni kwe-100cm kuya endaweni yengilazi ngaphandle kokulimala.
Ingilazi ye-SaysaNakekela yonke imininingwane ecela amakhasimende futhi woza isixazululo esihle kakhulu sephrojekthi yakho.
