Screw quiz ready!

The video quiz for screws is ready to go.  Sorry it took me a little longer to put together, I'll give you more time to finish it.  Let's say end of day Monday.

Make sure you've started those simple machine problems, so you can ask questions Friday.

HW 9-5: Video Quiz - Mechanical Advantage

Due Mon 9-8, 11:55PM
1.1 Video Quiz - Mechanical Advantage on Its Learning

• Watch the video 
• Answer 7 questions in the quiz
• You have 2 opportunities to take it.  Take your time and get it right.

Probably HW

What are the chances?
Head to Its Learning and check out either the PPT or the Video on Probability to help with the short quiz that follows.

THERMO! part 1

HW: D period (and observant and ambitious F period students)

• Watch the thermo-part 1 video
• Quiz on Its Learning

What could/should robots do for us?

CONTROL SYSTEMS

What could robots do for us?
What SHOULD robots do for us?

To begin exploring this idea, we'll study some programming.  Linked below is a programming aptitude test comprising of elements involving logical reasoning, numerical problem solving, pattern recognition, ability to follow complex procedures, and attention to detail. This does not require any knowledge of programming.  For some it comes naturally; some have to work at it, but everyone can code. Try your best, this will help me help you. 

1. Aptitude Test: http://www.kent.ac.uk/careers/tests/computer-test.htm
    
2. Submit this survey when finished.
    
3. HW: Where can and should we use robotics?  Answer the question and post a cool example of robotics (video/webpage/etc) HERE.

2.3 Material Testing Assignments

When considering materials, its important to test and understand their limits.  Specifically, we look at the stress a material is under and the strain that results and use that information to make decisions.

Assignments for 2.3 Material Testing

1. Tensile Testing video/quiz -due Sunday night on Its
2. Stress/Strain curve video/quiz - due Tuesday night on Its
3. 2.3.1 Stress-Strain Problems - due Friday in class

HW Thursday, 2-6: Tensile Testing

D & F periods
When considering materials, its important to test and understand their limits.
Watch the video below and take the short 5 question quiz on ITS


You have until Sunday night, 11:59pm.  Another video/quiz will post tomorrow as well as practice problems.

HW on hold

Technical difficulties prevented me from posting the video that was your HW tonight.  I have to record a new one, and that will take some time, so no HW tonight. I know you're sad.  It will be okay.  I'm sure you have HW in other courses.  Have a good night.

HW Monday, 1-13

D & F periods
Solve for the member forces on the truss below (the same one we did in class)

• isolate one joint at a time.
• draw an FBD for that joint
• Use trig to break member forces into x and y components
• ADx = ADcos()
• ADy = ADsin()
• set up equilibrium equations to solve for member forces
• Repeat until you solve for all member forces (hint: start at joints that have the least number of forces)

Knowns

• Ray = 66 2/3 lb;  Rby = 33 1/3 lb;  Rax = 0
• Fdy = -100 lb
• AC = 3', BC = 6', CD = 4'

How do I do this again? - http://youtu.be/cOSv5V9ShOs
