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.
There is one exception: You can borrow the post-tax money you've invested in a Roth IRA without being assessed a 10% penalty as long as you are careful to borrow only the amount you put in, not any earnings it made. See How to Use Your Roth IRA as an Emergency Fund for details.
