Notes+for+Today

Please continue working on refining this assignment:

You are using the VEX Cortex Robotic System. Please research at least 10 vex robots that accomplish different tasks and have a great "coolness" factor. This project will take three days to complete so don't just put up 10 pictures and figure it was a good job. I want you to discuss the structure, movement, sensors, and programming requirements of each robot. Make each robot that you report on "Come to Life".



See ya Tuesday :)

Bridges

Since we have been building bridges, I would like for you to research and prepare a PowerPoint comparing some of the interesting facts :)

Look at this site: [|List of US Bridges] and pick Five bridges to compose a PowerPoint Report. Please give pictures, movies maybe?, and definately fun facts.

See ya Wednesday .....

Only do what is above on Tuesday, January 24, 2012.

I will be out Today (I know you are still very sad ...). Please receive your quiz papers from the substitute and RETURN your quiz papers once you have finished. Yesterday's answers are (unless I made an error):

AX = 163.83 lb AY = 114.72 lb

BX = -163.83 lb BY = -114.72 lb

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">CX = 88,39 lb <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">CY = -88.39 lb

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">SumX = 88.39 lb <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">SumY = -88.39 lb

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Resultant Force = 125 lb <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Resultant angle = 45 degrees off of Y-axis in quadrant IV

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">You will continue to have a quiz each day ... (you are welcome :). When finished, please do some research on vectors and how engineers use vectors on their job. I plan to have this page updated each day, so ... I'll see ya in the real world Monday.

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Remember SOH CAH TOA

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">SIN = OPP / HYP <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">COS = ADJ / HYP <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">TAN = OPP / ADJ

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">What side do you <span style="color: #ff00ea; font-family: 'Comic Sans MS',cursive; font-size: 30px;">know and What side do you <span style="color: #ff00ea; font-family: 'Comic Sans MS',cursive; font-size: 30px;">want to know !!!

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Note: Theta is 20 degrees!



<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 260%;">Quiz for Today <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Problem 1) If side (c) is 10<span style="color: #ff00ea; font-family: 'Comic Sans MS',cursive; font-size: 30px;"> Meters then what is the length of the adjacent side?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Problem 2) If you do not know theta, but you know side (a) is 5 feet and side (b) is 50 feet, what is angle x? (You can look at the page: "Find the Angle" to help).

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Problem 3) Please draw a Free Body Diagram of a 70 lb. Lady Bug resting on a Golf Course ?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Problem 4) A 1st class lever system has a 400 lb. Gorilla resting 10 feet away from the fulcrum. You apply an equalizing force on the other side of the fulcrum with a distance of 80 feet.

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">a) What is your IMA?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">b) How much Effort Force must be applied to reach equilibrium?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">c) Now, in reality, you had to pushdown with 52 lbs of force. What would be the AMA?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">d) What is the Percent Efficentcy?

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">When you are done with the Quiz, continue working on the "Six Simple Machines", <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">power point.

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 30px;">Then work on making a bridge that will hold the truck with a cost that is below $150,000.00 ! I have seen some below $200,000 !!!!! <span style="color: #ff00ea; font-family: 'Comic Sans MS',cursive; font-size: 30px;">YOU CAN DO IT !!!
