~Dinamika Gerak Rotasi~Diketahui
mkatrol = 2 kg
mbeban = 1 kg
g = 10 m/s²
I = 1/2 m. R²
Ditanya
a =__?
Jawab
Maka, kita harus meninjau kedua benda maka
Tinjau katrol
Στ = Iα
Tr = 1/2. m. R² . a/r. 1/2
T = 1/2. 2. a
T = 1a
Maka, tinjau beban maka
Σf = m.a
W - T = ma
mg - T = ma
10 - T = 1a
Maka, percepatannya yaitu
10 - T = 1a
10 - 1a = 1a
10 = 1a + 1a
10 = 2a
10/2 = a
5 m/s²= a
Jadi, percepatan sistem katrolnya yaitu 5 m/s²
