1. A method for designing a drill bit, comprising: determining radial forces acting on a selected drill bit during simulated drilling; summing magnitudes of the radial forces with respect to a direction to generate a sum of the radial forces; comparing the sum of the radial forces to an applied weight on bit; generating a ratio between the sum of the radial forces and the applied weight on bit; adjusting at least one parameter of the selected drill bit based on the generated ratio until the magnitude of the radial forces remains at a value less than a predetermined value for a duration of a preselected amount of time during simulated drilling; and outputting a drill bit design based on the generated ratio and the adjusting.
