Q: The six 2" x 4" x 10' rafters that will support the roof can be fastened to the core box in one of two ways: the notch method or the hanger method. In either case, the front rafter and back rafter should be fastened flush with the front beam and the back beam. The remaining four rafters should be arranged equidistant from each other, along the length of the 16-foot side beams, about every 34 feet (0.91.2m). To notch the rafters, the idea is to rest them on edge of the beams. To do this, put the front rafter in position, and note where it comes into contact with the side beams with a pencil mark. At that point, notch the rafter with the circular saw so that in the finished position the rafter sinks about 1/3 of the four inches onto the beam. Once you are satisfied with how this first rafter rests on the side beams, take it down and use it as a template to notch the other five rafters. When fastening the rafters, angle nails through the side of the rafter into the beam below. Note that notching will not work if you need it to remain flush with the beam. To hang the rafters, buy some metal joist hangers at the hardware store. There are many different shapes and styles of metal hangers that fasten 2" x 4"s to other structural elements in a variety of orientations. The relevant angle in this structure, the angle of the rafters to the beams, is about 25 degrees. These metal hangers can bend to accommodate small variations, so don't worry about finding the perfect one. Unlike with the notch method, with the hanger method the rafters rest on top of the beams. Your nails will go through the hanger into the rafter, then into the beam. Arrange the plywood sheets so that they produce a six-inch overhang on the front and back of the carport as well. This way you will have a uniform look to the carport. Buy plywood sheets as large as you can get them. Typically, they come in 4' x 8' sheets, but sizes vary. The entire roof surface is 10' x 17'. Cut elements with the circular saw to produce the fewest number of seams. The fewer the seams, the less potential for water leakage. The core box of your carport is nine feet wide and the rafters are ten feet long. This means that when the roof elements are in place, you will need enough plywood for about a six-inch overhang on either side of the cart port. If you want it to be longer, accommodate by buying more plywood. Plywood comes in a variety of thicknesses. For this project you can use inch thick plywood. Now that the roof is in place, your structure should be quite solid. Nothing you do from this point in the process to the end will improve the carport's overall stability, so if there is excessive movement, you will have to add stability braces on the outside of the structure to reinforce it.
A: Fasten the rafters to the side beams. Fasten the plywood roof boards to the rafters. Check the stability of the structure.

Q: Select System Preferences, and then open Keyboard & Mouse. Under the Trackpad Gestures section, check the box labeled "Tap trackpad using two fingers for secondary click". This will enable you to right-click using two fingers. Note: Depending on your OS X version, the labeling may vary. On older versions, the box is labeled "Secondary Click" and is located in the Two Fingers section. Press two fingers to the trackpad to right-click an object. With the secondary click enabled, doing this will open the right-click menu.
A: Click the Apple menu. Click the Trackpad tab. Place your cursor over what you want to click.

Q: Use a measuring cup to mix equal parts of tap water and rubbing alcohol. You can either mix the solution in the measuring cup or pour it directly into a 20 fluid ounces (590ml) plastic water bottle. Rubbing alcohol can be purchased at your local pharmacy. Don't drink the mixture once you've made it since it's not safe to consume.
A: Mix 212floz (74ml) of cold water with 212floz (74ml) of rubbing alcohol.

Q: Which online database you use will depend on your location. Many are also very clear about what measures they use to protect anonymity. In the US, websites like condomfinder.org will enable you to find local organizations and businesses that distribute condoms for free. In England, the National Health Service maintains a searchable database of locations that distribute condoms. You can use it to find a distributor near you. If your department of health is distributing them, help yourself to a bunch so you will always be prepared! For example, New York City and the District of Columbia have large scale distribution programs. In places where large scale distribution programs are underway, free condoms may be available in local pharmacies, drugstores, or even grocery stores. Some physicians may give out free condoms. If you are a minor concerned about confidentiality, ask your doctor what his or her policy is. You can ask whether the information would be kept confidential from your parents. These organizations often offer condoms free of charge. You can call them ahead of time to ask if they are currently distributing. Possible sources include health clinics, gynecologists' offices, and hospitals. Planned Parenthood in the US often offers free condoms. For example, in Oregon you can drop in and receive 12 free condoms. It is confidential, even for minors. Many universities, both public and private, distribute free condoms to students in ways that are anonymous. The health center website will likely tell you exactly what is available, where you can get it and when it is available. You can also call the health center or drop by and ask. Chances are, you will be able to anonymously get more than enough condoms with no questions asked. High schools increasingly distribute condoms to students. High schools may make condoms available anonymously through vending machines or freely available in bowls or baskets. In other schools, students may need to obtain them from the school nurse, a counselor, health worker, or other personnel. Some schools have programs with where parents may decide whether these services will be available to their teen. Depending upon where you live, these services may even be available to you as a teen. Check the websites of organizations like TeenSource.org, LAcondom.com, or CondomUSA.com. Check the expiration date and do not use expired condoms. They are less reliable. As always, check the condom for tears or pinprick holes.
A:
Use online databases of free condom distribution points. Check with your local department of health. Ask your doctor. Try health clinics, particularly those that focus on sexual or reproductive health. Check with your university health center. Know what the sexual health resources are at your high school. Order free condoms online and let the condoms come to you.
