Explain the following:
The stone of a hand flour grinder(chakki) is provided with a handle near its edge.
Explain the following:
The stone of a hand flour grinder(chakki) is provided with a handle near its edge.
Prerequisite knowledge: Moment of force/torque
Explanation:
The formula used: ๐=Fรd
where ๐ is the moment of force/torque
F is the force
d is the perpendicular distance between the line of action of the force and the pivot.
So for constant torque, the force applied is inversely proportional to the perpendicular distance from the line of action of the force to the pivot.
The force is reduced by increasing the distance from the line of action of the force.
Conclusion:
The stone of hand flour grinder is provided with a handle near its edge so that it can be rotated easily about the iron pivot at its center by a small force applied at the handle.
