A second source of motion is elasticity in the bearing itself. For example, the balls in a ball bearing are like stiff rubber, and under load deform from round to a slightly flattened shape. The race is also elastic and develops a slight dent where the ball presses on it.
What to Expect for Refunds in 2015. The IRS issues more than 9 out of 10 refunds in less than 21 days. However, itâs possible your tax return may require additional review and take longer.
Once its accepted most returns are processed in 21 days or less and in many cases within one week. I think a lot of people are misunderstanding your question, and are answering how long it takes to RECEIVE your refund...not how long the IRS takes to approve that you're receiving a refund. 24 hours, though, usually. Any length of time. For simple returns where the taxpayer hasn't moved, hasn't changed jobs, isn't asking for credits and filed after the IRS had their W-2 on file, maybe 8 days. For everyone else, it could be 3 weeks (90%) to 6 months (the other 10%).
