12 cards from this deck
∑Fx=0\sum F_x = 0∑Fx=0
∑Fy=0\sum F_y = 0∑Fy=0
Object in equilibrium where all forces sum to zero
Identify forces → Resolve components → Apply ∑F=0\sum F = 0∑F=0 → Solve
12\frac{1}{2}21
32\frac{\sqrt{3}}{2}23
Yes, all concepts (equilibrium, F=maF=maF=ma, SUVAT) apply in 3D
Sum of all force vectors equals zero vector
x2+y2+z2\sqrt{x^2 + y^2 + z^2}x2+y2+z2
Same throughout the string
To split forces into horizontal and vertical parts
