From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. The sack hoist is a simple horizontal shaft and a rope that is tied to a grain sack. [50], In addition to meeting the stiffness, strength, and toughness requirements determined by the loading, the blade needs to be lightweight, and the weight of the blade scales with the cube of its radius. Initially, windmills were used for grinding grains. The sails or blades accumulate the wind that flows over it, and use the lift to turn the blades. The cap can be turned into the wind either by winches or gearing inside the cap or from a winch on the tail pole outside the mill.
