FULL  FACTORIAL DESIGN Stop angle has the largest impact on the distance traveled by the projectile while arm length and start angle are relatively similar in terms of significance. FRACTIONAL  FACTORIAL DESIGN The results are similar to the full factorial design as the most significant factor is the stop angle followed by arm length and start angle. CONCLUSION I would recommend the full factorial. As by having only 16 data points, we already have cut down the number of runs to 2 each. So the data is already not as reliable. If we did fractional factorial, it might not give enough data for us to get accurate analysis and the right interactions. Furthermore, doing a full factorial for 16 data points is not considerably difficult, hence there should be no issues with doing the full factorial.  

I choose the hinge as my 3D printing project because it could not be easily made substratively due to the exist of joint and complex design if using laser cutting. At first,I sketch the rectangle and a few circle . Then I extrude the sketch  and then extrude the circle so can make it as a joint. I construct the blue surface in the figure and make it as the mirror plane later.I use the mirror function so it will become the situation in the figure below. After that,I create new component from bodies and  set the midplane,I use again the mirror function so the both side will be same design. Then I copy the model so the two model will exist and I use the joint function to make them joint together.  I fillet the corner of the model as 4.5 mm After work is done, I save the file and export it as STL format. I open the Cura software and import the file which in STL format. I change the setting which is the speed to 60mm/s and build plate adhesion in brim type the click the slice ...

I programme the arduino board by using Arduino IDE app which installed in the laptop.After I connect the USB Micro Port B with arduino board and mt laptop,then I open the Arduino IDE app and go to    File > Examples > Servo > Sweep. Then I adjust the value for pos value in the void loop part, one is used to  control the servo from  0 o  to 180 o  and the other is used to control the servo from   180 o  to 0 o    .Besides I also adjust the value for delay part  .As I finish adjusting these value so I can get the speed of servo motor moving desired. The code below is the source codes I used  #include <Servo.h> Servo myservo;  // create servo object to control a servo // twelve servo objects can be created on most boards int pos = 0;    // variable to store the servo position   void setup() {   myservo.attach(9);  // attaches the servo on pin 9 to the servo object } void ...

 I am Peijie.From last semester ,I have learnt the fusion 360 skill from the Introduction To Chemical Product module.I will update my leant new skill here also same likes last semster,So there are two personal goals in this semster for me: a)master all the skill that have taught in eaxh lesson and put the effort as much as I can. b)communicate with teamates well so can avoid the situations like last semester which cannot work together . Since my old teamates,who are Clarence and Jiayu not same class with me in this semester, so I am grouped with Haijie and Yongjie.There what's we discuss about the team ground rules. a)All teamates should contribute ,so we can easily settle some homework by combining the teamwork and it can prevent the situation like last semester just one person to work. b)If someone cannot contribute should mention first so others can help and it doesn't matter to other if he mention before . c)we should build up a team with high teamwork spirit and it is not ...

A)START-UP turn on the air compressor at the back of the red switch turn on the switch of flip extractor turn on the switch of laser cutter, then wait until it completes initialization proceed to work station where we start setting our drawing to the laser cutter machine.   B)Operation of laser cutter including the basic use of Corel-Draw Open the cover fully to put your board into the machine. Close up the cover, make sure there are 2 green lights to confirm that the cover is closed properly. Import your DXF or SVG file into CORELDRAW OR design in the webpage. Set the line weight, colour and fill. Make sure all are the right colours for cutting, engraving and scoring.The red colour means cutting but the green colour means engraving.When we need to put some colour ,we need to adjust the value of the colour.For example, we will colour the shape that we wanna to cut with red colour and adjust its colour with 255 value but for other colour is zero.It is same to engraving by using gree...

  Firstly,I create a rectangle with 65mm length and 25mm width After I add the 2mm offset and fillet the 4 corners of rectangle and sketch dimension to it,I draw a circle with 5mm radius. THEN,I text my name inside the rectangle. After a few of process,the keychain have been done. In conclusion,the designation of keychain is a basic skill in fusion 360.When I design the keychain ,it was refresh my knowledge about how to use the basic skill of fusion 360 which we have learnt in last semester.I hope that I can be faster to master all the skill of fusion 360 so I can design the model that we will use in the following practical  in this semester.                                  https://a360.co/3bpIikQ WEEK 2 HANDPHONE DESIGN Firstly,I create two triangle and make dimesion to them about 4 mm for width and 120mm for length.Then adjust the angle about 72 degree for that like shown below. Then finish...
