<div>What was your original design plan? (zainab)</div><div>-Our original design plan was to have a structure that can lift weight using something that looks like a swing but doesn't have the sides locked in place. The structure was meant to look simple yet good enough for the criteria. It was always going to be a hydraulic device with 2-3 syringes attached. </div>
<div>What changes did your group have to make? (zainab)</div><div>-We just had to make a few changes so that our device could stay stable and could lift the weight without tripping or breaking apart. First, we had to add popsicle sticks on the sides of the swing so that when it lifts the weight, the load doesn't fall off the device. Secondly, we had to add more wooden sticks on to our device. We added wooden sticks in the middle of the device and a small piece near the end to make everything more stable so that our device stays stable and can be able to lift the load properly and safely. We also added another wooden stick right in the front of our device. The stick was added for the swing to be attached. Thirdly, we had to add wires near the syringe that is attached on the top so that when it lifts the load, our device can move up and down. Without the wires, it would be hard to bring back the swing down. Lastly, we had to add a bigger base so that our device could properly stand on a surface. The base we had earlier was much smaller and was made up of wood but it wasn't helping us in keeping the device stable without needing a hand to hold down the device.</div>
<div>What difficulties did your group encounter, and how did you deal with them? (zainab)</div><div>-There were about 2 things that we were trying to deal with and we succeeded in making it work. One of the things were to lift the 200g weight itself. At first, when we built our structure, it was hard for it to lift the weight and it was only able to lift about 100g. After adding more wooden sticks to the structure and adding popsicle sticks to the swing, it was able to carry 200g pretty easily and without any difficulties like tripping it over. The popsicle sticks allowed us to let the load stay on the swing without falling and the wooden sticks overall just helped our entire device to be able to effectively function and not break or stand unstable like it was before. Another thing was the base. At first when we built this, we only added a wooden block to attach the device on but then we realized that the base is too small and it's causing our device to trip over due to the fact that it has less room and support from the bottom part of our device. We added this thin plastic board/sheet, that held our device way better than the wooden base and kept it all stable and also easier to carry and move around.</div>
<div>How well did your product meet the criteria? (zainab)</div><div>-Our product met the criteria very well. It helped us understand how forces are transferred all around (knowledge). It also let us know the difference of compressibility of liquids and gases and how the usage affects hydraulic and pneumatic devices (application). We could tell the unsafe and safe uses of our product and it could also lift 200g higher than 5cm too.</div><div><br></div>
<div>Are there any things you would do differently next time? (zainab)</div><div>-If i were to make this again, I would plan it out better and have everything i need in advance. I would also use stronger materials for the swing and use a thicker wooden stick for the arm. I would try using less glue because in a lot of places, the glue has made it look messy. If we had this planned out better and we used better materials in the right places, then our product much have been even better than it is right now. </div>
