Center Of Gravity.   Without having been taught the concept of Center of Gravity, people (or insects and other mammals for that matter) understand solid objects have a center of gravity. Homogeneous means the density is uniform. The center of gravity of a flat uniformly dense object using moment Mx about the y-axis and My about the x-axis is derived. apparel mens tshirt ($15.00) womens tshirt ($15.00) sweatshirt ($25.00) sportshirt ($25.00) size Adult-3XL Adult-2XL Adult-XL Adult-L Adult-M Adult-S Youth-XL Youth-L Youth-M Youth-S Youth-XS placement front back quote (free!)   (quote to be emailed) Scott Adams - Creativity is allowing...
