However, Cauchy observed that the stress vector T {\displaystyle T} across a surface will always be a linear function of the surface's normal vector n {\displaystyle n} , the unit-length vector that is perpendicular to it.
Some do and some don't. A Nintendo Wii costs approximately $250 (the price range is $160-$380). <br /><br /> Don't forget that, in addition to the Wii itself, you have to buy games and controls; that'll cost an extra $50-$100.
