FIRST type of ramp construction of the model is performed using the following procedure: taking dimensions approximate to the blocks that make up the pyramid, using basic geometric shapes, a brief physical mathematical reasoning and common measures of length at that time; Choose an angle for the slope that permits almost completely cancel the action of the force of gravity; putting together a ramp that meets the two fundamental conditions: transforming work raise the blocks in overcoming the force of friction when dragging and not overcome the action of the force of gravity on them. Possibility of transferring blocks of comfortable, safe and quick way, making it possible to perform complex maneuvers with a minimum of risk; even if this involves travel greater distances and moving a greater number of pieces that make up the ramps because of the need to increase the volume and dimensions of the same. These two conditions of obligatory compliance for two types of ramps, constitute the theoretical premise that sustains this hypothesis. For the specific case of the model of ramp ready-made pattern to determine the angle of the slope, the measures used were employing Biblical ell as length: initial height: 0.45 meters (1 elbow), final height: 2.70 meters (6 bends, including the initial height), ramp length: 33.75 meters (75 elbows), width (optional): 1.8 meters (4 elbows) (width varies according to the height in case you of the second type of ramps) through the rectangle triangle theorem of Pythagoras, determines the angle of tilt that will take the slope, achieving the desired result. Randomly: not some specific procedure is used to calculate it. This procedure is reflected in the annexes. The measures are chosen according to the need of lifting objects up to certain height and position. Robotics gathered all the information. You can see how to design ramps of different lengths according to the foregoing in the annexes.
