I want to use a servo to rotate a solid disk that is 0.1m in diameter and 0.1kg in weight. If I use the following formula (mass moment of inertia);
I=1/2 mr^2
I=1/2(0.1kg)(0.1m)^2
I=0.0005kg∙m^2
Does this mean that I would need to apply a minimum of 0.0005kg of torque at 0.1m in order to make it rotate? If this is the case then a servo that can produce 1.6kg.cm (0.16kg at 0.1m) of torque would be more than adequate?
Thanks for getting back to me. The mass will be evenly distributed with little friction. I'm not sure what my angular requirements are at this stage except to say that I'm not looking for a rocket ship.
I'm curious to know how the torque given by servo manufacturers eg 1.6kg.cm relates to my project? In addition, I'm curious about what other factors/formulas I need to be aware of.
