Penjelasan:
m1 = 4 kg
m2 = 8 kg
g = 10 m/s²
Tinjau Gaya pada benda A :
F = m1 a
T1 - W1 = m1 a
T1 - m1 g = m1 a
T1 - 40 = 4a
T1 = 4a + 40 ... (i)
Tinjau Gaya pada benda B :
F = m2 a
W2 - T2 = m2 a
m2 g - T2 = m2 a
80 - T2 = 8a
T2 = 80 - 8a ... (ii)
Jika massa katrol diabaikan maka :
T1 = T2
4a + 40 = 80 - 8a
12a = 40
a = 3.33 m/s²
Tegangan tali :
T = 4a + 40
T = 4(3.33) + 40
T = 53.32 N
