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.
The IRS asks that you wait 3 days after filing electronically, or 3 weeks after mailing a return before checking for a status update. For those who file an amended return, however, the period to receive a refund check will take 8-12 weeks.
