Triangle The center of gravity of a triangle is at the intersection of lines BE and AD. The distance a can be calculated as a = h / 3 (2) Parallelogram The center of gravity of a parallelogram is at the intersection of the diagonals. Trapezoid The center of gravity of a trapezoid ca...
aTherefore, the center of gravity of any triangle is on each of the medians and thus is located attheir intersection. It was Archimedes who first conducted a detailed study of centers of gravity and who first proved this result. 所以,重心所有三角是在每一个中点和因而是被找出的attheir交叉点...
And Center of Gravity ... The Centroid is the average position of all the points of an object. ... When we cut a plane shape from a piece of card it balances perfectly on its
Center of Gravity of a Billiard Ball Array A common initial arrangement in pocket billiards has 15 object balls, each weighing 1.64 N, distributed symmetrically in a triangle, as suggested by the dot arrangement inFigure 3.43. The center-to-center distance of the billiard balls is 5.72 cm. Wh...
