Why do banked curves allow Indy cars to drive faster around them?

There's a whole lot of physics that goes along with an answer to a question like this, but the short answer is that if the track were not banked in the corners, the car would slide outward, and if the track is banked, the same force that is acting on the car to move it outward on the curve is now being used to push it down tighter to the track. The car can move faster through the corner because a lot of that lateral force is sort of converted to downforce. Unfortunately, Yahoo! Answers doesn't allow us to draw pictures.

What meds used during labor and delivery contain sulfa or iodine?

I am also highly allergic to Sulfa drugs. Thankfully no drugs used in childbirth contain sulfa, this is a drug which is predominently used in treating bacterial infections especially ear infections

Severe Anxiety/Post Partum Depression! Boyfriend doesn't understand! HELP PLZ!?

I had a baby in January. I was getting worried because my ex was coming around asking about my 3 yr. old. I talked to the doc about anxiety, she put me on 50 mg. zoloft. Within a month, my boyfriend and I were arguing more, I got jealous easy, anxiety wasnt helped and I became depressed. Doc put me on 100 mg. I have had panic attacks 3 times a week and get angry so easily/fighting with boyfriend all the time (never fought before this) He things meds are making me more crazy. I agree to an extent. I called doc again in hysterical in desperation after another attack. She told me 150mg. of zoloft. I said no, i dont want to take it anymore. She said Wellbutrin. I said the only thing I want to try is BusPar, (I read its good for anxiety and non-addicting)...Although actually I really dont want to take a pill everyday, I feel like I cry all the time because I cant control my anxiety, its a vicious cycle. I beg my boyfriend to understand, he in turn blows up at me!? What I really want is to get off all meds and just something like a valium or xanax for the time being until it dissipates. My doc wont do it. Why do I have to feel guilty to get treated for this when I clearly need it. I havent tried the buspar yet but I cannot bear to take something else that is going to make it worse. My relationship is in crumbles. I need advice please

Is it safe to machine wash Macbeth shoes?

Just try to clean them with a wet rag or something similar to be safe. I have never personally owned a pair of Macbeths but I have friends who have and they have fallen apart fairly easily. My personal experience with skate shoes is to just not wash them. Every pair of DC i have owned and washed fell apart, my Elements shrank, my Etnies got a hole in them in the wash, my Fallen got warped, its just not a good list for me. Also if your Macbeths were super expensive you may want to look into where you got them, back in the day when they first started they were pretty cheap because they were made for struggling skaters/musicians who needed fashionable and comfortable shoes on the cheap

I think I love him, but I dint know if he even likes me like that, and he has a girlfriend what do i do?

First advise, if you don't want it to be done to you, don't do it to another girl. Talk to him, have some self respect, from what you say, he is interested in you, but why is he with someone else? I don't think you should ruin this relation ship, if he really likes you, let him realize that he rather be with you, trust me, its not a good thing for you to get in between relation ships, you will end up hurting this girls feelings too.
