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.
Filing a return through the mail is, of course, the slower of the two processes. For those who mail their federal return, the IRS will remit a tax refund within six weeks after they have been received the completed return. If you file electronically, you should receive your tax refund within three weeks.
