yang pinter fisika bantuin please
Jawaban:
F1 = 25 N
F2 = 5 N
F3 = 21 N
F1x = -25 cos 53 = -25x0,6 = -15
F2x = -5 cos 45 = -5x 0,707 = -3,53
F3x = 21 cos 90 = 21x0 = 0
Fx = -15-3,53 + 0 = -18,53
F1y = 25 sin 53 = 25x0,8 = 20
F2y = -5 sin 45 = -5x 0,707 = -3,53
F3y = -21 sin 90 = -21x1 = -21
Fy = 20 -3,53-21 = -4,53
resultan
R² = 18,53² + 4,53² = 322,84
R = 18 N
θ = arc tan Fy/Fx = arc tan -4,53/-18,53 = 13,74⁰
Fy dan Fx negatif, lihat gambar di bawah
