a rolling grain mill having radius R is constrained to roll in a circle of radius r at a constat angular speed of W by a rigid shaft of negligible moment of inertia. For what value of W will the mill stone push on the floor with a force equal to twice its weight?(adsbygoogle = window.adsbygoogle || []).push({});

======================================================

my problem... i dont understand the question. does the question suggest that the faster the mill rolls, the larger the downward force? as in normal? pls offer your guidance and tell me what are the things i should look in order to solve this question. thx in advance...
