 Equilateral

In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. It is also a regular polygon, so it is also referred to as a regular triangle.

Quadrilateral

In Euclidean plane geometry, a quadrilateral is a polygon with four edges (sides) and four vertices (corners). Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon (5-sided) and hexagon (6-sided), or 4-gon for consistency with k-gons for arbitrary values of k.

What a Square is:

A square is a quadrilateral, which refers it to having 4 equal sides and 4 equal angles(90-degree angles also known as 4 90-degree angles).

What a Rectangle is:

A rectangle is a quadrilateral with 4 right angles(4 90-degree angles). It can also be known as an equiangular quadrilateral because all the angles are equal. It can also be known as an oblong, a non-square rectangle.

What a Parallelogram is:

A parallelogram is a simple quadrilateral with 2 pairs of parallel sides. The opposite/facing sides of a parallelogram are equal in length and the opposite angles of a parallelogram are equal as well. 

What a Trapezoid is:

On a trapezoid, the parallel sides are known as the legs and the other 2 sides are known as the legs. A trapezoid is similar to a trapezium but it has different angles and the parallel sides are uneven in size. There are many types of a trapezoid, one for example is an isosceles trapezoid(having 2 equal sides).

What a Kite is:

A kite shape is a geometric shape with 2 pairs of equal sides, it is also a quadrilateral shape. The inside of a kite shape can contain a perfectly measured circle that just brushes the sides. It can be either a concave or convex shape aswell.

Do you know the difference between a trapezium and a trapezoid?

Can Crusher Overall - Baylie

These are photos of the finished project I had completed recently called the can crusher. I had learnt skills like how to MIG weld and also gas weld, I had also learnt how to use the lathe. There are a lot of things I can improve such as my welding skill because my welds looked off at some parts. I had also MIG welded the endplate because of the issues of the gas welder that someone had tampered with. Overall it was a great project and it can show off your skills really well. I had a lot of fun doing it and I would like to see myself use these skills in the future.

Written Instructions

From: Administration

To: Staff Members

CC: Office Manager

Date: 18 August 2020

Subject: Fire Evacuation Instructions

Hello everyone,

The administration team have written a new set of fire evacuation instructions that will be sent through emails and will have copies of it around the main points of the workplace. Please read all instruction carefully and take them seriously.

1. When the fire alarm goes off everyone inside the building is expected to meet at the main assembly point.

2. Make sure there is nothing blocking the emergency exits.

3. Do not enter the building until you have been told it's clear by a fire safety officer.

I hope you guys can understand these rules clearly and abide by them if there are any problems let the administration team know. These rules can also be used for your own household if needed.

Cheers,

Meg Williams

Assistant Manager

Engineering Evidence Blog - Hand Tools

Baylie Raxworthy

132030449 

This is an entry-level unit standard for people to demonstrate a basic understanding of selecting, using and caring for the correct type of engineering hand tools. 

People credited with this unit standard are able to demonstrate knowledge of the selection of different types of hand tools; select and use engineering hand tools to meet task requirements; and care for engineering hand tools. 

Engineering hand tools applicable to this unit standard fall within the following categories:

 Cutting tools: examples – hacksaws, chisels, files, hole punches, tin snips. 

Assembly tools: examples – hammers, punches, vices, clamps, spanners, wrenches (including impact and torque), pliers.

My evidence to support my assessment booklet 

Cutting tools.

	Hack saw  In this photo I am using a 32 tpi hacksaw to cut my bar that is 410mm long 16mm wide and has a thickness of 4mm.
	Metal file  Here I am using a flat file to square my bar that is 410mm long 16mm wide and thickness of 4mm.
	Tin snips I am using tin snipes to cut sheet metal that is 110mm wide 65mm long and 1.5mm thick.

Assembly tools 

	Spanner or wrench I was tightening the nut on the mil for my work
	Hammer Here I am using a hammer and a centre punch to mark where I am going to drill an 8mm hole so I can place a bolt into it.
	Gripping tools I am using a clamp to hold my work together to wield to create a frame for my project.

What have I learnt?

I learnt how to use a range of hand tools during the year since this is my first year in engineering. I have gained a bunch of experience around tools, what they do, and how to use them.

What was the most difficult tool to use and why?

I think the file was one of the most difficult to use just because it was very time consuming and you had to try to make everything as square as possible.

What did I enjoy?

I enjoyed wielding the frame because it was satisfying watching it come together.

What would I do differently next time?

Faster production definitely so I can meet the deadline and start another project.

This supports the assessment for Hand Tools that can be found on this website https://sites.google.com/hornby.school.nz/mr-r-manufacturing/senior-manufactring/hand-tools

Review

RE: Use of Bins

4 August 2020

To: Jenny McCabe

Hello Jenny,

I am writing this review to inform you about the behaviour of the staff and their use of the bins.

• The food bin is not empty often which leaves a bad odour and mould growth
• They think it is a waste of time putting the bins out
• They often forget what bin to place their items in

Those are the mains points of what the current situation is but other than that the system is going well.

Regards,

John Flon
