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.
If you electronically filed an income tax return, then you can expect that your refund will be issued within 21 business days. If you have submitted a paper income tax return, then the processing time for these returns can take 8-10 weeks. Some returns, whether electronic or paper, are randomly selected for review.
