Tension Test

I applied downward pressure onto the lever of a wooden clothespin resting on the balcony tiles. The internal steel coil resisted before yielding, parting the twin wooden jaws. Maintaining balance with one knee against the concrete, I nudged a flat grey pebble between the teeth and eased my grip. The spring snapped shut, locking the stone firmly in place. Propping the clamped pin against the base of a heavy terracotta planter created a steady forty-five-degree brace. The assembly held firm against minor surface drafts. Mechanical potential confirmed.
