Is there a formal way of telling if my data is normally distributed? I know I could plot a histogram for the data, and see if it follows a bell shaped curve, but I need something a lot more formal than this. Is there a way to do it? Thanks

I have a physics question that states: An amount of positive charge is distributed uniformly along the positive y-axis between y=o and y=a. A negative point charge -q lies on the positive x=axis a distance r from the origin. Derive the x and y compontes of the force that the charge distribution...

In static problems, an evenly distributed load can be made into a point-force by multiplying the load by its length, and so this point-force will now act in the center of the distributed load. This is cool, but I can't find out how to do the same thing with loads that are unevenly distributed...

Not really something I would expect most people to know so I will keep it out of the Homework help section (it is not homework) I am working on distributed strain sensing with fibre optic Bragg gratings for aircraft. For those that don't know, FO Bragg gratings are a periodic variation in...

I can’t get in the picture below which power I will get on the wheel, i am guessing that there will be an resultant on 45 degree with a force of around400*9,82 N. http://img33.imageshack.us/img33/2695/problemhjul4rh.jpg Thx for any help given

ive posted this in the other forum, but haven't received a reply, so trying again :) Question: -straight wire with radius R, carrying current I -current is uniformly distributed across the cross sectional area of wire -calculate the magnetic field inside wire as function of distance r from...

Suppose that X and Y are independent random variables, where X is normally distributed with mean 45 and standard deviation 0.5 and Y is normally distributed with mean 20 and standard deviation 0.1. (a) Find \ P(40 \leq X \leq 50, \ 20 \leq Y \leq 25). Ans. ~0.5 (b) Find \...

Hi, I'm trying to prove if X~Po(m) => 2X~Po(2m) But I'm not sure how to prove or disprove it. I'm thinking about using the addition formula, but is this the right approach? X_1~Po(m) X_2~Po(n) X_1+X_2~Po(m+n) n=m => X_1=X_2 => 2X_1~Po(2m) Any help is appreciate. Thanks /farbror

Do any of our members use any distributed computing apps? If so, what do you use, and for what reason? What are your favourites? I ran SETI@home (like almost everyone else on earth, I think. ;) ) for quite a while, achieving 221 data units in 7,000 hours. But recently I've switched to...
