Articulated structure for the study of the mechanics of rigid bodies. This invention is a mechanical structure in wood type matched with 20 mm thick consisting of three curves whose extreme points (I, f) have the height y2 = 50 cm and Y1 = 20 cm. Its width is x2 = 70 cm. The curves if, although they are different, they have equal length (m (FIS) = 1 m).Each one of them completes itself in three angles equal to 30 244 198 198, 45 and 60 198. Under these conditions, the curve for the angle 244 = 60 198 is the most fundamental, while that for 244 = 30 198 smoother.The receptacle of the projectiles of dimensions X1 = 40 cm and Y1 = 20 cm has the quantity of waste wood, "maravalha", enough so that this becomes the same height at the point F, which corresponds to the time the initial launch of missiles or mobile elements, as we have called. This residue has the function to absorb the impact of projectiles and also record the exact point of these impacts.The movable elements are classified geometrically as spheres, discs and rings, and on the adhesion, coating adhesive, coating and without adhesive. On each turn, was set at a strip of plywood 3 mm of the same length of the curve and 2.5 cm in width, and about this, he settled a strip of white Formica equal dimensions except the thickness.
