Pneumatic tools

 

1. What are Pneumatic tools/air compressors? Diagram examples of compressors and an explanation.

Show a range of different air compressors you might come across.

-What are pneumatic tools? Pneumatic tools are powered by compressed air. Common types of

these air-powered hand tools that are used in industry include buffers, nailing and stapling guns,

grinders, drills, jackhammers, chipping hammers, riveting guns, sanders, and wrenches.

2. Safety when using an air compressor. Dangers and hazards, preventive action, and servicing.

• Always wear proper PPE and make sure the tool is working just fine.PPE that needs to be

• worn includes everything from safety glasses w/ side shields, full-face shields, face

masks, hearing protection, and sometimes even respiratory protection. 

3. PPE when using air tools - general 

Wear safety glasses or face shields, safety shoes, or boots.

4. Different types of air tool connections /tools

There are many different types of air fittings but most air tools use one of just a few types of

connector. The main things to consider are the fitting type and the thread size. Common
fixing types include ¼” BSP, ¼” PCL, and 3/8” NPT.
   

5. Specific safety when using

 

Impact driver - when using an air-impact wrench. Tie long hair back or secure under a cap. Wear

hearing protection when using this tool; an air-impact wrench creates a noise exposure of about

103 dB. Use clean, dry air at the manufacturer's recommended pressure (about 90 psi) to power

the air-impact wrench.

Air ratchet - Always wear safety glasses with side protectors when using an impact wrench. Never

wear a tie, loose clothing, a watch, rings, or jewelry when using an air-impact wrench. wrench. Only use impact wrench sockets that are specifically designed for this type of tool.

Dust off gun - A "quiet" nozzle (i.e. one with low noise emission) should be selected. Use effective guarding

methods that prevent a chip or particle (of any size) from being blown into the eyes or unbroken

skin of the operator or other workers nearby. You may also use barriers, baffles, or screens to

protect other workers near the operator if there is a risk of exposure.

  

Air riveter - Eye protection must always be worn by the operator to guard against flying fasteners

and debris. Keep unnecessary personnel away from the work area. Keep away from heat sources

and flammable substances. Risk Level Medium Control Measures Wear sunscreen, hat, long

sleeves, and long pants.

 

Bivariate Data and Vitruvian man - Maths

 Does our class have the perfect body form?

Who is a Vitruvian man? The Vitruvian man is a drawing made by the Italian polymath Leonardo da Vinci 

What is a Vitruvian man? Leonardo da Vinci's drawing of a male figure perfectly inscribed in a circle and square, known as the "Vitruvian Man," illustrates what he believed to be a divine connection between the human form and the universe. Beloved for its beauty and symbolic power, it is one of the most famous images in the world.

 

Q - Question	Do we have the perfect body proportion?
P - Participants / Sample	I’m going to be measuring 12 boys heights and arm span from my maths class
V - Variables and Values	My two variables are arm span and height
R - Relationship

S - Step by step	Get all the participants Participants take off their shoes A participant stands up straight on the whiteboard Using a tape measure, measure their height from toe to top of the head Once again we use a tape measure, participant stands up against the whiteboard with their arms stretched out and measure their arm span
C - Control factors	Controlling and avoiding mistakes, taking off shoes, etc
C - Conditions	Using measuring tapes
R - Repeat	Repeating the measurements

I collected my data and plotted the information onto google spreadsheets.

Analysis

Trend - The trend on this graph is a strong Linear graph. You can see that it is all bunched up together which makes it a positive linear graph. 

Direction - This graph is strongly Increasing. It is going upwards along the best fit line.

Strength - The strength on this graph is moderately strong. It is all bunched together.

Unusuals/outliers -  There are 3 outliers in this graph. The 3 outliers are the ones way off the best fit line.

Conclusion

Does our class have the perfect body proportions? Yes, I think the data I have collected shows that  95% of the class has got the perfect body proportions. We can see this in the trend, direction, and strength of the graph. The data that has been captured is a strong linear increasing scatter graph.

Maths - Area of basic shapes

Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).

Pythagoras therom - Maths

Pythagoras theorem - a theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

Pythagoras, who is he? Where did he live and what did he do?Pythagoras was a Greek philosopher and mathematician.He lived in Metapontum village and Cortona. He made important developments in mathematics, astronomy, and the theory of music.

Triangle facts - Maths

Triangle facts - There are always going to be 3 sides.

                       - All angles add up to 180 degrees

                       -A triangle can always be split into 2 right angles no matter how it is constructed

  

                       

Different types of triangles - Equilateral triangle = all sides are equal

                                            - Obtuse = greater than 90 degrees

                                            -Acute = Less than 90 degrees

                                            - Scalene = None of the sides are the same

                                            -Right angle triangle = one angle is 90 degrees

                                            -Isosceles = 2 sides are always equal

MATHS - Volume

What is volume - In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.                                                                                                                                                                                                                                                                                                              formula for volume - Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.    

English - Freedom Writers

 Unpacking themes and ideas.

Theme/Idea - the ideas the story centers around. - message we are trying to convey to the audience.

Tolerance - the quality of allowing other people to have their own attitudes, beliefs, or to behave in a particular way, even if we don't agree or approve.   

Overcoming Adversity - Pushing past/getting through something difficult or dangerous.  

The students don't respect or have a relationship with their teacher. They don't understand each other. They drew a racist picture of Jamal. The students yell at the teachers, face different directions, tell her they don't give her respect.

Andre - "why should I give my respect to you? Because you're a teacher? I don't know you. How do I know you're not a liar standing up there" 

They aren't in a headspace to learn because they don't feel safe-bring guns to school, mock each other, no tolerance for each other. Marcus - " Lady, I'm lucky if I make it to 18, we in a war! We graduating every day we live because we ain't afraid to die protecting our own"
