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.
It can take up to 21 calendar days after acceptance for the IRS to issue your refund, although most refunds go more quickly than that, while a small handful may take a bit longer. Start tracking your federal refund at the IRS Where's My Refund site. For state refunds, go to your state government's refund lookup service.
