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 will take 10 days to issue a refund on an electronically filed return. The IRS will take four weeks to receive a mailed return and process it into a form in which it can then move on to a similar process for issuing refunds as on e-filed returns. Refund checks will take 10 days to get to you via mail.
