/**
 * Calculate bearing L10 life.
 * L10 = (C/P)^p x 10^6 revolutions
 * L10h = L10 / (60 x rpm) hours
 *
 * p = 3 for ball bearings
 * p = 10/3 for roller bearings
 *
 * The exponents are not free parameters: they come from the Lundberg-Palmgren fatigue
 * model and are what makes this the *basic* rating life, the life 90% of a large group
 * of apparently identical bearings reaches or exceeds. A caller wanting a modified life
 * has to apply the reliability and operating-condition factors on top; this returns the
 * unadjusted figure.
 *
 * @reference ISO 281, basic dynamic load rating and basic rating life.
 *
 * @throws RangeError if dynamicLoadRating, equivalentLoad, or rpm is not positive
