2 Zitsanzo za mafunso okhudza kufanana kwa tinthu tating'onoting'ono
1. Chinthu cholemera makilogalamu 10 chimapachikidwa pa chingwe. Dziwani mphamvu ya chingwe (T)! g = 10 m/s2
Zokambirana
2. Chinthu chimapachikidwa pa zingwe ziwiri monga momwe chithunzichi chikusonyezera. Kulemera kwa chinthucho = 10 kg. Mphamvu ya kukakamira pakati pa zingwe ziwiri zothandizira katunduyo ndi…
Zokambirana
(chithunzi chakumanzere) katundu, chingwe ndi chothandizira, (chithunzi chakumanja) chithunzi cha mphamvu zomwe zikugwira ntchito pa katundu.
Mawu ofotokozera:
w = mphamvu yokoka ya chinthu = mg = (10 kg)(10 m/s2) = 100 kg m/s2
T1 = mphamvu yogwira chingwe 1
T1x = mphamvu ya chingwe 1 pa x-axis = T1 45o = 0,7 T1
T1y = mphamvu ya chingwe 1 pa y-axis = T1 tchimo 45o = 0,7 T1
T2 = mphamvu yogwira chingwe 2
T2x = mphamvu ya chingwe 2 pa x-axis = T2 45o = 0,7 T2
T2y = mphamvu ya chingwe 2 pa y-axis = T2 tchimo 45o = 0,7 T2
Mkhalidwe 1 : chinthu chili mu static equilibrium ngati mphamvu yochokera pa chinthucho ili ndi zero.
Taganizirani zigawo za mphamvu zomwe zimagwira ntchito molunjika (y-axis).
Tsopano ganizirani zigawo za mphamvu zomwe zimagwira ntchito mopingasa (x-axis).
