This is an Action Project for my core class Urban Planning. This unit has been all about bridges, equations, gravity, and Newton's Laws. This action project requires us to make a bridge out of popsicle sticks and glue. We are going to take the bridge and put 1 gallon of water on top of it to see if it will not break. This is an excellent idea because it shows gravity and its effect on objects. Newtons three laws are 1. An object will not change its motion unless acted on by an outside force. 2. F = M x A. 3. Every action has an equal and opposite reaction. With these bridges, we also need to calculate the Potential/Kinetic energies, angles, and lengths of each triangle in the bridge. Below is an image demonstrating the parts of my bridge that experience compression/tension, and all of the important pieces of the bridge. CJH/Bridge Visualisation/2021 Calculations: How many sticks did you use? A t least 60 sticks. How high will you bridge be when you put a gallon of water on it? 3
