How to workout if a network is transferable

Leonhard Euler

Euler was a prolific mathematician whose work spanned the fields of geometry, calculus, trigonometry, algebra, number theory, physics, lunar theory, and even astronomy. Euler's contemporary colleagues, and even mathematicians working today, recognize him as one of the greatest mathematicians to have ever lived.

Konigsberg Bridge

The Königsberg bridge problem was an old puzzle concerning the possibility of finding a path over every one of seven bridges that span a forked river flowing past an island—but without crossing any bridge twice. Euler argued that no such path exists.

What is a network

A network is simply a collection of connected objects. We refer to the objects as nodes or vertices and usually draw them as points. In mathematics, networks are often referred to as graphs, and the area of mathematics concerning the study of graphs is called graph theory.

Rules of a transferable network

Rule 1: All Nodes have to be even 

Rule 2: If there are two odd nodes this can also be considered a transferable network but you have to start and finish on the odd node

Rule 3: If there is more than two odd nodes then the network cannot be a transferable network

Evidence for Hand tools

 My evidence to support my Hand tools assessment booklet 

Cutting tools.

	Hack saw  Here is a photo of me using a 32 TPI hacksaw to cut out my pole to 90mm to be used as a push rod for my can crusher
	Metal file  I'm using a Flat file to file down a 20 by 4 bar to 90mm to be used as a cross brace for the base of my can crusher.
	Tin snips I'm using the tin snips to cut out the corners for my flat faceplate which is used for my can crusher

Assembly tools 

	Spanner or wrench In this image, I'm using a spanner to loosen the bolt so that I could be able to change and adjust the angle on the mill machine.
	Hammer In this image, I'm using a hammer to hit a centre punch to mark a centre point to drill a hole on my lever which is for my can crusher.
	Gripping tools In this image, I'm using a vice to hold my bar while I file my bar for my can crusher.

What have I learned?

I have learnt a whole variety of hand tools in the past few months and has helped me a lot and would come in handed in the future if I come around anything that's got to do with hand tools

What was the most difficult tool to use and why?

Using the tin snips was a bit difficult for me as it took a lot of pratice to get my work accurate and straight because before my cuts were off and not accurate and straight.

What did I enjoy?

I enjoyed learning how to use a different variety of tools in the workshop and also improving each time I use them and making my work look better and tidy.

What would I do differently next time?

Question for the future reference?

Would we be using these types of hand tools in workshops or in the future?

Can Crusher

This year in Engineering we are making a can crusher and a gear knob for our projects. I am in the process of making a can crusher and almost done. In the past few weeks of making the can crusher I have learned how to gas and MIG weld in the workshop. By using oxygen and acetylene I joined and connected the two pieces of metal together to create the base of my can crusher.

Here is the final outcome of my can crusher, I'm really surprised and happy with the outcome. Throughout the process, I enjoyed learning how to use a different variety of tools and machinery. Learning how to use the Gas welder was the most enjoyable to learn and use as it was something different than the MIG weld, with this one you had to use a filler rod and also holding the torch, unlike the MIG weld where your only just holding the torch in your hand. It was difficult at the start and then I started to get the hang of it. But overall I really enjoyed creating and making the can crusher.

Amazon Rainforest

Matses were a tribe or Jaguar people that lived along the Javari river in the remote areas of the Amazon Rainforest in Peru and Brazil. In the early 1990s, the Matses were not interested in money because they had little access to shop in their remote area of the Amazon Rainforest. Matses lived a different lifestyle, On hunting wild games, such as the peccary and tapir with bows and arrows and fishing as their primary food source, farming crops such as sweet plantain and manioc, and the collection of wild foods. To Matses, plants and animals have spirits just as humans do, and can ail or heal a human body. In the last thirty years, Matses have become a largely settled people, living mostly in permanent forest settlements. They started to contact with the outsiders, missionaries encourage assimilation into a modern culture so that they could improve access to trade goods and they started to began living in larger, fixed, super nucleated villages along the rivers. Now Matses are starting to be involved in the sustainable harvesting and marketing of natural products. They are harvesting renewable and valuable tree resins, such as copaiba and Sangre de Grado, they can earn money they need but be free of destructive and dangerous forestry jobs.

Bushfire Presentation

My presentation went well I had some great information about bushfires and it was also good to learn about something new while I was creating this presentation. I think I could've done more and found more information about bushfires. I can now understand the differences between cultural and natural in social studies
