nail holding power increases with increasing moisture content in wood ?

No, nail holding power actually decreases with increasing moisture content in wood. Moisture causes wood to swell, which reduces the grip and holding power of nails. Drier wood provides a better surface for nails to hold onto, resulting in increased nail holding power.

No, the nail holding power does not increase with increasing moisture content in wood. In fact, it decreases. When wood is dry, it is harder and denser, allowing the nails to grip and hold more effectively. Moisture in wood causes it to soften and swell, which reduces the nail's holding power. Therefore, it is recommended to use dry wood for better nail holding strength.
