1. The problem statement, all variables and given/known data heres a very messy drawing for an idea of what were looking at: http://img89.imageshack.us/img89/1764/untitledyi0.png area moment of inertia Ix0 of a rectangle about the axis x0 that passes through the centroid is: Ix = 1/12bh^3 the moment of inertia about an axis x that is parallel to the x0 is given by: Ix = Ix0 + Ad^2x where A is the area of the rectangle, and dx is the distance between the two axes. the inputs are width w, height h, and thickness t. w = 200mm h = 300 mm, and t = 22mm find the moment of inertia: 2. Relevant equations Ix0 = 1/12bh^3 Ix = Ix0 + Ad^2x 3. The attempt at a solution my questions are.. is t the what plugs into b in this problem? also, is area of the rectangle just Base * height, so 200 * 300? not sure how to find the distance between the two axis. please help.
