Timber hitches are used to secure a line to logs, planks, or other rough surface material objects.

• A. Rough surface material
• B. Logs
• C. Smooth surface material
• D. Rounded surface objects

Answer: (C)

Timber hitches rely on friction created by wrapping the rope around a rough surface. The irregularities in rough wood—like logs or rough planks—grip the rope as tension increases, so the line stays secure when hauled or tied off. On smooth surfaces, there’s little to bite into, and the rope can slide, making the hitch unreliable. So the key idea is that timber hitches are for securing a line to rough surface material objects.
