Engineering 1 ktran

In today class, we went over the engineering economics. -We draw a cash flow diagram. Then we calculate it based on the formula given : P: principal i: interest rate n: time in year - We next calculated the simple and compound interest then graphed it in the same graph. -Here are some exercises to practice calculating the amount that one needs to pay out montly - Also calculated the amount of principal from initial to come up with the future fund needed. Here is the other way around which is calculating the amount of future fund based on given principal and interest rate and time in year and also month. - Got one more practice using excel to calculate how much time it take to pay off credit debt when pay $50 and $100 a month. - Lastly, we testes our bridges and recorded the amount off Force that our bridges can handle before breaking. Also to see who builds the best bridge 

In today class, we learned dimensions, units in U.S and other countries. -We started off by measuring the dimension of the wood block. - Then we list the unit of U.S and S.I There are some commons in unit of both U.S and S.I  such as second, mol,... - Then we learned about understanding the meaning of formula based on unit  -After that, we calculated the volume of the soda can and estimate our difference with true value. -  - Next thing we done was looking at the picture of a sumo and a model, then gave the prediction on who will cause much more damage when step on our foot.  - Last thing we did in class was using spaghetti to build a bridge which can handle amount of mass 100g-1000g. -Our group was successfully with handling 500g of mass on the bridge, but we were not able to handle 1000g.

In today class (Wednesday 11/01/2017) - We started by learning new code and set up for more challenges in today lass. - We did autonomous code so our robot can go entire circle without using the control - We had a little bit problem with coding because the computer stopped working accidentally. Luckily, with the help of Professor Mason and the member of Robotic team we could make it to the next round of competition. - Next challenge was to go around the field using control, and grab a cone. After that, we had to press a button to activate autonomous mode for the robot running to the designated position and drop the cone. - We did not do well at the beginning, but the last challenge where each team we combined all the code learned from the beginning of the class and download to the robot. We won in the last competition and became one of the winning teams. -This was so much fun building and learning things about robot. It definitely helped us understand more about this inte...
