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 you filed your taxes and the IRS accepts the filing, your refund (by check or direct deposit) should be on its way within 21 days if you file electronically, or up to six weeks if you file a paper return by mail.
