Anthropometrics, Ergonomics and Standard Distribution Curve

Anthropometrics
Definition - anthropometry, especially as it relates to the design of furniture and machinery.

 

Ergonomics
Definition - the study of people's efficiency in their working environment.
Standard distribution curve 

There are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a "Normal Distribution" like this:

A Normal Distribution

The "Bell Curve" is a Normal Distribution. 

And the yellow histogram shows some data that 

follows it closely, but not perfectly (which is usual).

GIF's I made

Wood design for my dad

I am going to design and manufacture a Toolbox for my dad and I'm making this because my dads old toolbox 

is slowly breaking apart soI’mm going to make him a new one the purpose will hold all his tools like screwdrivers

screws hammers and stuff like that think dad will put it in the laundry and then he won’t have to go out to the

shed and bring in a broken box  

The measurement I think I would want to use for making this box is a 14″ 

The specifications for this is going to have is 

• no loose parts
• both compartments and lid fits perfectly
• it has enough room to fit tools like hammer, nails, drills, screws etc.
• it doesn't take up to much room  
• easy to carry
• doesn't fall apart
• The handle is on tight and doesn't fall off 

My build a Boat

Boat Practical and Learning The Gantt Chart

In our class I really enjoyed the learning of use making the boat, but actually in this practical Mr. Rees wanted us to know and be familiarised on Gantt Chart. Gantt chart is used by builders to have a timetable like for construction. Anyway, we started with our 1st class with giving out these papers—boat dimensions and outline planning.

Materials that we used.

This was the first step for our project. Sawed the wood into 320mm

The outcome of our first lesson should be this.

This is the bridge measurement.

In the end, the bridge should look like this.

We call this part the channel. We chiseled it out using chisel and wood hammer.

Then, we glued the bridge to the base.

Lastly, we glued the funnel to our boat.

Here's my boat while I'm waiting for the oil to dry.

Just to give you an idea, our last step on making our boat was to add some oil on it. Mr's tip was to go with the grain if you're adding oil, in order to show it's total beauty.

Lastly, these boats are my classmates finished products.

Earlier, Mr. Rees made us make another copy of our Gantt Chart. On the paper Gantt chart, it was our estimated time and this electronic version is what was the actual time it took me to build the boat.

Mr. Rees made us to do this because he want's us to learn how gantt charts work and how does it apply in the real world.

My really cool math project

In Maths you won't believe I actually did work aha joking me Madd and Conrad were working on Google sites on Google sites we learned about percentages fractions and decimals

Link to my Sites
In this, we Have put information about Contractions Decimals Fractions and Percentages

This project was really fun Me Maddy and Conrad were joking around at the start but we got it finished it isn't good but it isn't bad

We found the information on Maths is fun we got all the information we needed plus examples

Do you think I missed anything out?
Would you try google sites or Maths is fun?

Our class treaty was made together as a class on the 9th of Feb
