2020 L2 Evidence for Dimensional measuring equipment

  US 4435 v8  Level 2 Credits 3 

Your name: Joshua Irwin

NSI Number:0132439384


People credited with this unit standard are able to – select; use; and care for engineering dimensional measuring equipment. 


Examples of engineering dimensional measuring equipment are – vernier callipers; internal, external, and depth micrometers; dial test indicator (DTI); height gauges; steel rules.


To pass this assessment I need to provide evidence that I can  select  the correct equipment in accordance with the geometry of the object to be measured, likely magnitude of dimensions, and required accuracy. 

I also need to show that I can carry out equipment checks before use and any faults are reported, examples are – deformation, breakages, stickiness, not zeroing, missing parts, expired calibration. 


My evidence to support  my assessment booklet will need to show a micrometer; vernier callipers; and two other items of dimensional measuring equipment from the list above.


My evidence of using Dimensional measuring equipment.

Please include  evidence of you using the dimensional measuring equipment

Vernier Caliper

Konigsberg bridge

 


Euler's Solution of Seven Bridges of Königsberg in Layman Terms -  Mathematics Stack ExchangeLeonhard Euler - Education, Facts & Early Life - Biography

Leonhard Euler was one of math's most pioneering thinkers, establishing a career as an academy scholar and contributing greatly to the fields of geometry, trigonometry and calculus, among many others

The Konigsberg bridge has 7 bridges and has 4 odd nodes making it impossible to cross the bridges once so the network is not transferable 

On August 26, 1735, Euler presents a paper containing the solution to the Konigsberg bridge problem.  He addresses both this specific problem, as well as a general solution with any number of landmasses and any number of bridges.  This paper, called ‘Solutio problematis ad geometriam situs pertinent is,’ was later published in 1741 [Hopkins, 2].  Euler’s paper is divided into twenty-one numbered paragraphs, and in what follows, a simplified version of Euler’s paragraphs will be presented.

information from: https://www.maa.org/press/periodicals/convergence/leonard-eulers-solution-to-the-konigsberg-bridge-problem 

what is a node:

node or a vertex of a network is one of the objects that are connected together. The connections between the nodes are called edges or links. A network with 10 nodes or a vertices and 11 edges (or links.

is the Konigsberg bridge transferable on its network:

The Konigsberg Bridges are not transferable only a even number of bridges can give you the right results.

My Question:

Why are there only 7 bridges and why is it so important?

 i would  use these locking pliers to get in the complicated welding spots for the side rails of my can crusher 


What have I learnt?

i learnt how to use all these different tools and got my knowledge from my friend and the internet 


What was the most difficult tool to use and why?

filing made me very impatient and took to long making my arms tired going back and forwards with

the file


What did I enjoy?

using the hacksaw was enjoyable because there's there's more going on there than the other tools

i have used

L2 mathematical shapes and terms

mathematical shapes and Terms  

a square has four parallel and equal sides and has an angle of  90° each is 360° 4 = 90° so every angle of a square is a right angle.

 Square PNG
rhombus has four equal sides. The opposite sides are parallel, but the corners do not form right angles. A diamond shape is a good example of a rhombus. 
Is a parallelogram also a rhombus? Why? - Quora
A rectangle has four sides where everything is right sided yet again every angle is 90°and also a rectangle doesn't have equal sides around the shape.
Rectangle - Wikipedia

Diamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal. And, because its opposite sides are parallel, it's also considered to be a parallelogram.
What is a Diamond? | wild.maths.org


Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles and (3) perpendicular diagonals. Other important polygon properties to be familiar with include trapezoid properties, parallelogram properties, rhombus properties, and rectangle and square properties.

Engineering L2 Project power tools

 L2 Engineering power tools 

here are some of the evidence i have of me using power tools


i used a size 8 drill piece for the side rail for the can crusher before using a size 8 drill i used a smaller drill to make a hole for the size 8 drill piece 




i was using the grinder to smooth out the cross brace and the right and left hand rail after welding them together.

Engineering L2 Projects #2 hand tools

 Evidence of using 3 different hand tools

here are some photos of me using these tools for evidence for my can crusher and gear knob


Engineering L2 Project

 Evidence of my Can Crusher 

This is my can crusher for my first project i have enjoyed making this and learning what i needed to do in order to complete this project 

 i ended up getting a size 8 nut and bolt and now i have completed my can crusher. I've tested it out and it did pretty good. 

i wished i would've picked better colors for the can crusher and re sized the wood base.
