From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent – a wind turbine – can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and ...

5.3 grinding forces, power, and specific energy Forces are developed between the wheel and the workpiece owing to the grinding action. For plunge grinding operations, as illustrated in Figure 5-2 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a tangential component F t and a normal component F n .
