The three-cup anemometer was further modified by the Australian Derek Weston in 1991 to measure both wind direction and wind speed. Weston added a tag to one cup, which causes the cupwheel speed to increase and decrease as the tag moves alternately with and against the wind.
A A. There are certain restrictions when it comes to borrowing money from your Roth IRA. While you can't take out a loan from your Roth IRA like you can with other retirement accounts such as a 401(k), you may withdraw funds for short periods of time. The withdrawal of these funds are tax-free, penalty-free and interest-free, according to Bible Money Matters.
Withdraw the amount of your contributions. You can't borrow from your Roth IRA once the tax year is over, but you can withdraw funds up to the amount of your contributions without any type of penalty. If you invested $2,000 in 2007 and $4,000 in 2008, you can withdraw up to $6,000 without incurring a penalty.
