How do you go around a curve?



What is the safe way to go around a curve?

What does it mean to bank a curve?

Who controls what?

So, there's yellow light ahead. You have jackrabbit drivers, overly cautious drivers, tired drivers, and poor brakes. You have single roads, double lanes, and overpasses...

What things can engineers control as they design the intersection? What things can you control?

Factors involving Yellow lights (20 pt)

How does the two stop light system in downtown Manchester differ from the light bank found in a city, where six or seven yellow lights in a row can be found? Give me a concrete example (Dubuque, CR, etc.) and your belief about what factors can change.


Text your group hypothesis to me regarding the use of the final yellow light simulation found on the last blog post. You need to explore safety and stopping mechanism, or stopping mechanism and flow rate in some way.

Write your whiteboard up with a procedure and a data table.

Those Yellow Lights




Why do we need yellow lights?

Why do we seem to hit several lights in a row as either being green or being red?

Should we speed through yellow lights?

Blogsphere Land


Good morning! As you have probably guessed, I am not in the classroom today. I expect you to be doing a variety of things with your lab partners, including making a poster worth 20 points. The groups for today's poster are:

Group 1: Bryan, Ted, Tory
Group 2: Amie, Claire, Cari
Group 3: Tea, Summer, Jordan
Group 4: Dalton, Jennie, Kyle
Group 5: Ryan, Joe, Josh
Group 6: Erin, Lexi, Jon S.
Group 7: Tabitha
Group 8: Michael R

Assignment:
===============
1. The computer lab is not available today. Make due with the computers we have in the classroom, please. Go to here sometime during the day today and nominate a teacher that has made a difference in your life. It can be anyone in your life who has believed in your abilities and it is a chance for them to be recognized. Txt me when you are done with this step...just say, "This is _____--done."

2. You are traveling down a road and a deer runs out. Quick, what do you do? Click Here for a list of ideas (I have run several copies for the substitute, so please get one per group). Circle the three things that you think are most important.

Now, imagine you need to communicate this information to others in a VISUAL manner, with a maximum of ten words on the paper. Make a poster to explain how reaction time and equipment condition can help you to avoid the deer or minimize the collision. How would this be different if you were going around a curve at the time of the deer sighting? Hand this in before you leave today. Linsay and Jordan can help you find colored pencils or markers. After you do this, you may move back to your table

3. Read pp. 36 in your book and use the information to answer Q 1-8 on p. 40

4. Make a graph with speed on the x-axis and stopping distance on the y-axis for the picture at the top of this post(again, I have run several copies of this) and hand in with your name on it.



Thank you for being such a good sport! I really really appreciate it.

See you tomorrow.

Stopping Distance

As you double your speed from 20 mph to 40 mph, what do you think will happen to the distance you need to come to a complete stop? Estimate in terms of a number (E.G., 1.5 times, 3 times, etc.)

Tuesday, September 2, 2008

Give details of how you accelerate when:

a) you come to a stop sign
b) you go around a curve
c) you are coming onto an on-ramp for Hwy 20.
