Using a toy car we made in an earlier exercise, we would like to test air flow around the car.

1. Design a tunnel
2. Put a car in it
3. Analyze air flow in the tunnel.
4. Make an animation of air flow and upload it to youtube.
5. Post a link here.

Complete the tutorial “SOLIDWORKS FloXpress” and record the animation using https://screencast-o-matic.com/screen-recorder. Upload them to YouTube and post a link here.

How are you today? How was the homework? What was/is the most challenging step for completing this HW?

Please make parts in the handout that I gave. Assemble all of them and make an animation using a mechanical mate.

Watch the following Arbor Press animation that I uploaded. Distance Mate.

We want to assemble this Arbor Press today.

1) Download the zip folder https://drive.google.com/file/d/16Cr3Iv69goMqRNWgA4sHc8O2Wa9w2lyS/view?usp=sharing and unzip it (right click and select “extract”).

2) Open a new assembly file and import all part files.

3) Assemble them based on the image the Arbor Press that you’ve watched in the youtube video. In terms of the rack and the pinion (gear), we have to set up a special mate called rack pinion of “mechanical mates”. I put an instruction video here:

4) After finishing 3), create an animation of Arbor Press which moves pressing down and lifting up. You can motorize it using linear motion (actuator) or rotation motion (motor). (Maybe you can try a linear motion that we haven’t done yet in the class.)

5) Upload your animation to youtube and post the link here!

6) We will discuss this animation next week before the midterm starts.

That’s it!! Enjoy!

Who is in the classroom now? How are you today and how was the exam? Was it difficult to understand or easy to solve?

Who is in the classroom now? Are you ready for the midterm exam today?

Look at the handout that we have (EX12-18 Millimeters)

We have 6 parts: 1) Web Plate, 2) Drive link, 3) Center Link, 4) Rocker link, 5) a 10mm-diameter shaft (10mm long), 6) a 10mm-diameter shaft (15mm long)

I. Create all parts using solidworks
II. Assemble all of them as shown in the handout,
III. Make an animation: Drive link should be motorized and rotate clockwise with either 10 rpm or 60 rpm.
IV. Upload the animation to youtube and post a link to this post.

Who is in the classroom now? How was HW? Was it difficult or easy?

1. Make two dynamic animations using 2-inch balls and 4-inch balls.
2. Modify the slopes using the mirror feature and create another set of slopes. simulate 1-inch balls.
