Analyze vector mechanics by altering weights. Calculate the unknown total internal angle (θ), then verify using the components breakdown section below.
Because the central junction ring remains completely static, the system satisfies Static Equilibrium (Net Force = 0). This implies the pulling components must balance perfectly across both horizontal and vertical axes.
The left horizontal component fights off the right horizontal component:
T1 * sin(α) = T2 * sin(β)
Since hanging weights m1 and m2 create the cord tensions directly, T1 = m1 * g and T2 = m2 * g.
The vertical lift components of both cords join forces to support the central load weight (m3):
T1 * cos(α) + T2 * cos(β) = m3 * g
