Description: Experiment Purpose: recognize mechanics transfer and mechanics balance Experimental Cognition: Bridge Pier and Deck: environmental protection wood composition, versatility, odorless, pollution-free, is the mainstay of the cable-stayed bridge structure Experimental Report: The the bridge main load is not the car or train above it, but its weight, mainly the main beam. The pylon is symmetrical on both sides of the cable, through the stay cable pylon girder connected together. It is assumed that there are only two stay cables on each side of the tower, one on each side, and the two stay cables are subjected to the gravity of the main girder to generate two symmetrical tensile forces along the stay cables in the tower. To be Analysised, the left side of the force can be broken down into a horizontal force to the left and a vertical force; the same right of the force can be broken down into a horizontal force to the right and a downward force; as both each force is symmetrical so that the two forces horizontal to the left and horizontal to the right cancel each other out, eventually the weight of the main girder becomes two vertically downward forces on the pylon, so that the force is transmitted to the bottom of the pylon pier Color: wood color Material: wood Specification: Experiment Steps: 1.
