PR. 4 Engineering Class

 

       PRINCIPLES OF ENGINEERING I 

Good Afternoon.  Today 10-6-21 you will continue working on the crane problem.  You should have all completed the below for the crane problem to date:

1) Problem statement

2) Research ideas saved to google doc with problem statement

3) Sketch ideas created, discussed among team members

4) Best solution selected

5) Collect materials and begin redesign build

NOTES for class:

All materials needed will be on the front table next to my desk.  I think most groups have supplies to begin the project.  Remember the supplies follow the guidelines as attempt #1.

If you complete the crane and are ready to test, go to the cantilever page on the blog and complete "Crane strain #2"  

         

           BEFROE WEIGHT TEST IS PERFORMED 

YOU MUST WEIGH YOUR CRAINE

MAKE THE PREDICTION BEFORE YOU TEST IT

COLOR RED WHERE YOU EXPECT FAILURE

TAKE A PICTURE BEFORE YOU TEST

TAKE A VIDEO OR SEVERAL PICTURES AS YOU TEST

Engineering Trivia Game compete against your classmates

ASSIGNMENT  Create a document and submit it to the google assignment and answer the questions below. 

1)Explain the areas most interest you and what specifically about this area peaks your interest.   Beyond saying it's "cool"  what makes it cool, interesting, exciting, well paying etc. 

 

2)If you were working in the field of your choice, and you could choose what project you would be working on what would it be? why that?

4)Take a moment to consider the down stream affects of how your solution could affect generations to come, explain why there would be minimal affects or potential ones. 


YOU DONT NEED TO DO THIS SECTION 
I would also like you to create 3 questions that can be used for the questions and answer sessions with the Engineers at Husky.  They do not have to be specific to their operations and practices, however they may be if you wish.  Any questions you have thought about in your research around engineering, college, the transition, we can discuss this more in class

Fluid Dynamics: Pneumatic & Hydraulic Systems

Hydraulic Systems 

Pre-Assessment

Proficiency to be studied

Abilities for a Technological World

Students will develop the ability to intentionally apply the design process,
implementation of tools and machines to model, test, troubleshoot, observe, investigate,
and analyze the relationship between solutions and assess impacts on all
technological products and systems.

Standard 12.  Students will develop the abilities to use and maintain technological products and systems.

These will be added to and updated.

Assignments ~ Please follow the links to complete each assignment below.  Please do them in order as they appear.  Please make certain you read the description of each activity and the directions in their entirety as you work through the experiments.  

#1) Pneumatic Vs. Hydraulic Activity Sheet~ This experiment helps you form a basic understanding of the difference between pneumatic  and hydraulics.  Please follow the directions of the sheet to perform both activities.  Please read the questions before you do each activity, so you have an understanding of what you should be observing during the activity.



#2 How Do Hydraulic Systems Work? 

This document gives you an overview of how how systems work together as they are integrated with either hydraulics or pneumatics' 

#3 Wisc Online Tutorials ~ Go through the tutorials below learning how Hydraulic cylinders provide forces where needed and how they act when certain forces are applied back as a load 

     A) Hydraulic System 

     B) Hydraulic Pump Example  

    C) Pneumatics Vs. Hydraulics 

#4)  States of Matter
I will present this topic to the class.  You will need the information contained with in this presentation to answer the questions for the document in #4 & #5 

#5)  Hydraulics~Energy & Power

#6)  Fluid Power Systems Questions 

Pascals Law 

Watch the video below to develop an understanding of how Pascals Law works with-in a system

#7) Assignment: Complete tutorials below submit your final score to the assignment in the classroom

Understanding Pascals Law 

Before we get the the robot design elements.  Lets research concepts behind the mechanisms that will be used to make the robot operate. More explanation in class
