These stone grinders are used for many purposes like splitting the pulses, commonly known as Dal and then dehusking from those pieces. Traditional Stone Grain Grinder consists of two circular-shaped stones. The lower stone is mainly stationary and is called quern and upper hand rotating stone is called Muller or hand stone [2].

The only forces acting on the stone at the instant of your diagram are 1) gravity and 2) the string pulling on the stone. These two forces exist whether or not the stone is rotating and are the only two forces acting on the stone. Force 1) gravity, always points down towards the earth. Force 2) the tension points along the string, away from the ...
