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

ROBOT DESIGN BUILD PROJECT  

This is a comprehensive document of a major project that will encompass your learning during the semester.  Below are the learning targets and proficiencies  

3 View/Isometric Drawing

                                             ENGINEERED DRAWINGS
                                     &
                                        COMMUNICATION  

Developing new products, inventions and innovations are always communicated through engineered drawings, which are used as a way to communicate information to Designers and Engineers.
Interpreting The importance of Engineering Drawings, the information they communicate about the design/information is critically important.  

Uniform standards 

By using uniform standards, processes and tools it creates a level playing field for like or common information across all sectors of the world.   The current conventions you will use to communicate drawing information is called ANSI, American National Standard.  By using specific conventions, Engineers and Designers have a uniform way to communicate all information needed to create a part, size, material, tolerances and more.  This is important these areas are standardized so no further information needs to be communicated to the fabricator, for production.  This decreases the need for lead time and any confusion about final production.

2. 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 11.  Students will develop the abilities to apply the design process.

Indicator R: Evaluate final solutions and communicate observation, processes, and results of the entire design process, using verbal, graphic, quantitative, virtual, and written means, in addition to three-dimensional models.

3. Design and Application

Students will identify and develop an awareness of the attributes of design and engineering practices, the role of research and development, invention and innovation, and experimentation play in developing solutions to a problem.  

5. The Designed World

Students will learn to turn resources, materials, tools, machines, people, information,
energy, capital and time into useful products and systems.

 Standard #17 Students will develop an understanding of and be able to select and use information
and communication technologies

Indicator P: Students will develop an understanding of and be able to select and use information and communication technologies.  In order to select, use, and understand information and communication technologies, students should learn that:  There are many ways to communicate information, such as graphic and electronic means.
