F S H A P E

Here is what my F Shape looks like when I finished it. It was a long process but I got there at the end. First of we had to grab this long metal piece and we had to cut two pieces into 60mm the tool I used to cut it was called a backsaw and then we had to clean our metal to take the dirt off the metal so it can be clean so we can add engineer blue on to it so we can get a perfect and straight line. To get the measurement correct we used this tool called a Vernier which was very helpful, All you do is just adjust it to get the perfect measurement. Another Tool that you could use for measurement is a ruler and a try square. I also used the drill to drill a hole in my work because it could also be used as a keychain. 

Safety rules for the Drill are that you have to have 2 people with you the reason is that if the power button is far away from the drill and the other reason is that if something happens like your hair get stuck and you cant reach it the second person cant just turn it off. Before you drill in your work you have to put your work in and tighten it so when you drill in your work it won't come loose and not go flying off. 

At the end of all the process, we sand our work to get engineer blue off and then we finished off our work with spray paint.

Ergonomics
Human factors and ergonomics, is the application of psychological and physiological
principles to the design of products, processes, and systems.




Standard Distribution Curve
About 68% of values drawn from a normal distribution are within one standard
deviation away from the mean; about 95% of the values lie within two standard
deviations; and about 99.7% are within three standard deviations.
This fact is known as the 68-95-99.7 (empirical) rule, or the 3-sigma rule.

Technology has changed a lot of things for the better.
But can tech also have a negative impact on us? I think that there are positive and negative impacts on our life. One of the negatives that technology impacts us is by losing too many jobs.
Machines are taking over our jobs so people like farmers and other people don't have enough money to
support themselves or their families.


Definition of Technology- Machinery and devices that impacts the community by different things.
