Duck weathervane

Duck weathervane is a tool which is used to envisage the direction of wind. It is a movable device which is attached to any elevated object mostly roof. They are balanced in such a way that half of its weight is on either side of its axis and the areas exposed to air on both sides are unequal. It minimizes the force of wind and cause vane to rotate. It is also known as wind vane.

Duck weather vane includes full bodied metal figure with metal spacer balls, solid metal directionals, and roof mount. Popular types of duck weather vanes are small duck weather vane, copper duck with fish weather vane, hand hammered styling duck weather vanes and copper duck weather vane etc.

Duck weathervane is a duck shaped plate which is mounted on a vertical pivot or axle. So a small force at a lengthy distance can conquer a larger force at a small distance. Now the tail of a weathervane could consequently actually have a smaller area than the head but still rotate the vane if it is placed sufficiently far from the pivot.

Portion of weathervane with greater surface area gives more resistance to wind which causes the vane to take position in such a way that the forward part points in direction of wind. By the help of compass rose we can determine the direction of wind.
