Summary of assignments and schedule

Here are the assignments you have been working on and what is coming up after break.

Make sure you followed the directions carefully for each assignment.

b) Read the Bridge Project Rules - http://mrandradesphysics.blogspot.com/2012/02/bridge-project-rulesrequirements.html

c) Look at some other bridge designs and how they will be tested:

d) design your bridge using the knowledge you gained from the bridges webquest and following the rules and requirements. Make sure you have a drawing with 3 views, dimensions and a list of how many of each length pieces you will need.

e) have your design checked by me

f) build your bridge following the tips in the manufacturing reference

g) test the bridges

h) fill out the project report packet (which you will get on testing day)

Bridge Project Rules/Requirements

The requirements for the bridges you will build are listed below.

You must have a design drawn before you may start construction.

Also, read the Engineering Design Process and Manufacturing Process before starting.

You can read it here: https://docs.google.com/document/pub?id=1ck86UADuxbOyz0Uk2GmwSu4Re7FQuP5jHgyItmnUHoY

Rules and Requirements

Students will build model bridges. The bridge that can hold the most weight wins.

Bridges have to be between 250mm and 300mm long and width must be between 50mm and 75mm wide.

The bridges must be less than 100mm high.

The only materials you will have are a knife, working surfaces, ruler, 15 pieces of balsa wood, and glue. The balsa wood pieces are 61 cm long and 4mm square.

You can NOT laminate the wood - in other words, you can NOT have pieces of wood glued together lengthwise to create a larger surface, like a board. See me if you have questions.

You will not have to build any legs or supports - that will be done with books.

Your design should be well thought out. You should have drawing of your design (3 views - side, top, front). 

You should estimate how many different pieces of different size cuts of wood you will need. Cut them out, and start assembling them in different sub-assemblies.

You should also create a template where you can lay the wood on the paper and then glue it.

We will start building the bridges after you have done your research and designed your bridge.

g) test the bridges

Reminder, again, regarding class work

REMEMBER - everyone in the group is working on the assignment at the same time. You do not take turns. You must all be paying attention to the assignment all the time. If you are taking turns, and other members of the group are not paying attention or are talking about other subjects, you will not get full credit for the assignment.

This is nothing new. We have been doing this since the beginning of the year and the rules are the same. You must ALL be paying attention to the software or simulations or research, ALL the time, no matter who is actually controlling the computer.

Bridges Webquest

Before you do the bridge design, building, analysis and testing, you need to learn a little about bridges and bridge design.

Go to this link and follow the directions and links:

–https://docs.google.com//document/pub?id=1A6R5eXNZtN96l-kbBGZqgQbZtNwqusUVP0k_tFgd6G0 

You will be going to different websites (click the blue links) and then answering the questions, writing observations, and so forth. Make sure you pay attention to the directions and each student must turn in their own paper.

Stress Computer Assignment

•
Stress computer assignment

Multimedia Science School (software)

Physics
Mechanics
Materials 

Lesson
Stretching Materials

Each student submits their own: explain in your own words, what you learned, how did stress and force apply in this, show any and all calculations and answers to questions done during lesson. How can you apply this information to something in your life?

Solids - Stress, strain, fracture

Today, Thursday, Period 1 and 3 had the lecture for Solids - Stress, strain, and fracture.
Friday, Periods 4 and 6 will have it.

Here are the lecture notes:

Homework is Packet #9, exercises 1-9

Next we will do some virtual labs on stress and strain, then a webquest on Bridges and then you will design, analyze, build and test bridges.
