Suppose a pair of rolling element bearings is being considered as the support for the front wheel of a bicycle. The bicycle is to be used as the primary means of transportation to and from work. The one-way distance is 4.0 miles. (Other than for the commute, the bike is seldom used). What load rating should be used to ensure with 99.0% confidence that both front-wheel bearings last 3 years? State all significant assumptions.
