# Pulley block: share a load between supporting rope segments
# Scope: Ideal massless frictionless reeving; count only segments supporting the moving block. Block geometry is schematic; rope routing is omitted.
load = 200 N
segments = 4 in 2..8
lift = 200 mm in 100..250
effort := load / segments [N]
mechanicalAdvantage := segments
ropeTravel := lift * segments [mm]
part fixed "Fixed block": box 80 mm, 20 mm, 20 mm at 0 mm, 0 mm, 300 mm
part moving "Moving block": box 80 mm, 20 mm, 20 mm at 0 mm, 0 mm, lift
check pulling force: effort <= 60 N
scenario fewer supporting segments: segments = 2
