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. The IRS allows two options for receiving a federal tax refund: paper check sent via the mail, or an electronic funds transfer (also called a direct deposit). The direct deposit method, not surprisingly, is always the quicker option.
