activity 3.1.3

Activity 3.1.1 Inputs and Outputs: Learned basics of inputs and outputs and how digital and analog inputs behave in addition to open and closed circuits

Activity 3.1.2 Flowcharts: Designed flowcharts for various operations

Completed Flowcharts from Activity Sheet

Activity 3.1.3 Basic Programming: Learned functions of robopro and how to make a flowchart that controls the actions of the motor

Here were the Conclusion questions for this program :

Activity 3.1.4 Branch Functions:Used new flowchart object in order to allow computer to make decisions using criteria based on empirical data.

Activity 3.1.5 Variable Functions:  Created a program that controls the number of times a light turns on and off using variable program blocks.

Conclusion:

1.    Describe how you might modify the Plus command so that it can reset a variable block to 0 within a program.

Change the plus to a minus.In order to keep track of data
 2.What might an industrial or manufacturing engineering need to count or keep track of? Describe one example.

It would be necessary to keep track of how many operations or tasks have been completed.

Activity 3.1.6 Open Closed Loop Systems:

For this activity we created a train type system in which the motor moved forward and backward on a track.

activity 2.1.7

Here is my completed work for Activity 2.1.7 : Calculating Truss Forces. During class we have been learning about how to build stable bridges as a lead up to our final Design and Bridge Building Challenge. I will be posting about the challenge soon.

bridge building

We just finished the wrap up to the bridge building lessons that we have been completing over the past few weeks. After learning how to calculate truss forces and moments we were able to create a stronger bridge. To test strength of the bridges, magazines were placed on the bridge until the bridge collapsed. My team's design was one truss( since we could only use 3 folders making a true bridge with double truss and a connector would go over the folder limit. The triangle design held but gave in on the asymmetrical side by the 12 magazine. At least it was better than the first time around.

Here is a video of the final test

     Over the past month, I have been in need of a new gaming PC, so I started doing work for my dad and in about three months I came up with just enough money for all the parts I need. It took me a while to assemble a list of all the best components in my price range, but once I did, I assembled it and started playing. The assembly was quite the adventure for me because I had absolutely no background knowledge in the process, but once I it started it all made sense from there.

our marble sorter for principles of engineering

    In the past few week of my engineering class,my group (Isaiah, Ian, Shana) and I, have been working and testing ways to sort at least three different kinds of marbles. We constructed a device using fisher tech equipment and some other materials to separate wood, metal, and glass marbles. To separate the wood and metal from the glass we found that the glass were slightly bigger that the wood and metal, so we made a section of the track small enough for the glass ones to role on but big enough for the wood and metal ones to fall through. To separate the wood marbles form the metal ones, we used fans to blow the wood ones out of the way but not the metal ones, because the wood ones were significantly lighter than the metal ones.  Another aspect of the challenge was to make a funnel to set the marbles in to the sorter, for this we made a cone-like structure out of styro-paper and cardboard. When we were ready for our final test we came across some complications, first was the funnel, when we dropped the marbles they would jam at the exit of the funnel. Another complication that we came across was that when it came time for the wood to be separated from the metal, the marbles would be going too fast and wouldn't be affected by the fan. With a few modifications,  we were on our way to a semi functional marble sorter.
