Answer 2

1. (F1 + F4) - (F2 + F3)

= (600N + 100N) - (400N + 300N)

= 700N - 700N = 0N

 ΣF = 0N

2. F1 + F3 - F2

= 400N + 100N - 200N

= 500N - 200N = 300N

ΣF = 300N

3. (F1 + F2 + F3 + F4) - (F5 + F6)

= (30N + 35N + 35N + 30N) - (40N + 25N)

= 130N - 65N = 65N

ΣF = 65N

4. F1 + F2.cos a - F3

= 200N + 300N × cos 30° - 250N

= 200N + 300N × 1/2√3 - 250N

= 200N + 150√3 N - 250N

= 350√3N - 250N

= 100√3 N atau 100 × 1,73 (√3 = 1,73)

ΣF = 100√3N atau 173N

5. F1 - F2

= 200N × cos 45° - 300N × cos 30°

= 200N × 1/2√2 - 300N × 1/2√3

= 100√2N - 150√3N

= (√2 = 1,41 dan √3 = 1,73)

= 100 × 1,41 - 150 × 1,73

= 141N - 259,5N = -118,5N

ΣF = -118,5N

semoga membantu

maaf kalau salah
