If you do not have a text message from Uber, tap "Resend" to receive a new code. When you receive that code, enter it into the app. This will verify your account and have you ready to ride. If you still have not received a code, you'll need to report the issue to Uber using a form on their help site. If you do not receive the text message containing the verification code, your mobile carrier may be blocking a form of text message called "short code SMS." Contact your cellular provider and confirm that "short code SMS" is enabled for your account. Log in to the Uber website with your username and password. Point your web browser to this form on the Uber help site. In the field labeled "Phone Number," enter your phone number and click "Submit." Uber will now verify your account and contact you when the process is complete.

Problem: Write an article based on this summary: Stretch to open up your airways for easier breathing. Stand with proper posture to open your airways and make deep breaths possible. Practice belly breathing to help you hold notes longer. Hum scales to improve your hearing and control. Train your voice to sing certain notes using solfege syllables. Use digital tools to fine tune your voice. Train with a vocal coach to get an outsider's perspective.

Answer: To stretch before singing, first you want to bend over until your hands almost reach the floor. While in that position, inhale deeply for about 3 seconds. Then, exhale slowly. Repeat the breaths 2-3 times to elongate your airways and prepare your body for singing longer notes. Have a chair or something nearby to hold on to in case you get dizzy doing this stretch. To sing in tune, you have to be able to hold your breath long enough to carry the note. To stand so that you can maximize your breaths, roll your shoulders back and down, make sure your chin is parallel to the floor, and put your hands relaxed at your sides. Standing with very straight posture can feel awkward if you are not used to it, but the more you practice, the more natural it will feel. Belly breathing, also called diaphragmatic breathing, is essential to master and get comfortable doing if you want to be a singer. To breathe from your belly, relax your chest and shoulders and focus on pushing out your belly as you take a deep breath in. You should see your belly expand as you do it. Then, exhale deeply, concentrating on contracting your stomach muscles and bringing your belly back to its resting state. The best way to get comfortable belly breathing is to practice it often so that it becomes natural for you to do. Watch yourself practice belly breathing in front of a mirror. Make sure you can clearly see your belly expanding and contracting and not your chest rising and falling. Warm up your voice and practice hitting the correct pitch by humming notes in your range from lower notes to higher ones. Use online videos or audio recordings to hear the various scales and record yourself humming back the sounds you hear. Compare the recordings of yourself with the originals, identify where you don't sound the same, and keep making new recordings until you can't hear a difference between the two. Humming is a great way to prepare for in-tune singing because it warms up your voice without putting stress on your vocal chords. You have likely heard of solfege syllables before. They are notes usually sung in scales to the sounds of Do-Re-Mi-Fa-Sol-La-Ti-Do. Practice making the different sounds of the scales using the solfege syllables in order. Then, change it up and move around the scale to improve your hearing and pitch. Solfege syllables are great for training your voice because they are simple one-syllable sounds that flow easily from one to the next. Children's music teachers rely on teaching sounds with solfege syllables because they provide an easy way for anyone to associate the short sounds with the musical notes. There are a lot of digital tools available that will tell you the notes that you are singing so you can practice getting the right ones. You can get a digital tuner from a music store or an online retailer, or there are numerous apps available for download on your phone or tablet. Practice control of your voice using the digital tools' feedback to make adjustments. Look for digital tuner apps like ClearTune or Tonal Energy. Even famous and highly-skilled singers work with vocal coaches to constantly improve their skills. Vocal coaches are trained to identify issues with your singing and teach you exercises that will help you improve. If you are able, working with a vocal coach is a great idea for learning to master singing in tune. In the U.S., check the database of the National Association of Teachers of Singing to find a register vocal coach near you. Or, ask around to musicians you know or stop in a local music shop to ask if they have lessons or can direct you somewhere that does.

Problem: Write an article based on this summary: Gather your materials. Determine the thickness of your sheet. Calculate your bend allowance. Mark your bend lines. Cut your sheet to size.

Answer:
Having the right tools on hand will help this process go smoothly and quickly. To bend your sheet metal with a vise and hammer, you will need: 2 wooden or metal form blocks Block of hardwood and heavy-duty hammer or mallet (optional) Calculator or online bend calculator Marker Protractor Rubber, plastic, or rawhide mallet Ruler or tape measure Sheet metal Vise You can use a tape measure or ruler to measure the thickness of your sheet metal. This measurement will be necessary for calculating your bend allowance. If your sheet metal is too thick, you may need special machinery, like a brake or a torch, to bend your sheet into the desired shape. The bending you will be doing will warp your sheet metal so that it is physically bigger. To calculate the expansion that will take place on the outside of your bend angle, you will need to know your bend allowance. You can find your bend allowance with the following formula: (/180) x B x (IR + K x MT) = bend allowance (BA), where B is the angle complementary to your desired bend angle (1 to 180 degrees), MT is the thickness of the material, IR is the inside radius, and K is the K-factor. To ascertain your K-Factor, inside radius, and material thickness (expressed as a decimal), you should use an Bend Allowance Chart. As an example, if you want to bend 24 gauge sheet metal at a 90 angle, the calculation would be: 0.017453 x 90 x (0.020 + 0.33 x 0.024) = 0.0438558984 inch bend allowance Keep in mind that some metals are more brittle than others. Bending a brittle metal beyond its limits could cause the metal to snap and break. Now that you know your bend allowance, take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal. Then use your bend allowance to draw your second bend line, the intervening distance between your bend lines (bend radius). The space between your bend lines will expand with the application of your bend. You should leave a little trim to your sheet, approximately " is recommended. Be sure you file and smooth your sheet, as nicks and rough edges can cause cracks to form in your metal.
