Paper airplanes

Paper airplanes are the perfect scale models of real flying Gliders. Two challenges longest flight and longest distance. Even though my plane had a smaller wingspan we decided to use it in the longest flight.

My plane was pretty balenced with thrust,weight,Drag and lift. My plane was based on a jet. Smaller wingspan many Flaps and lots of speed. After the design was done I thought it would have the actions of a jet but it was the complete opposite. My plane managed to fly for 5.06 second. It practically  floated down to earth. After revaluation of the airplane I released there was a little pocket under the wing that allowed lift and send wind directly to the Flaps allowing it to gain altitude or to keep the airplane balenced depending on the wind.

Forces Of Flight

What are the four forces that allow an airplane to fly?
Four forces cause an aircraft to fly in the air. Lift,Thrust,Drag and Weight.

What is thrust?
"Thrust" is commonly used to describe how the aircraft moves itself through the air without loosing airspeed.

How do engines on airplanes propel the aircraft forward?
Just like a boat the propeller propels the aircraft through the air. The shaft cuts the air on an angle that creates air flow which moves the aircraft giving is thrust.

What is newton's third law?
Newtons Third Law stated that every action has an opposite. Which simple is anything that goes up must come down. Gravity is why flying is so complex even though there is only for steps.

What is lift?
Lift which is created by the wing of the aircraft. The wings allow pressure on the top and bottom of the wings allowing the wing cut the air and letting the aircraft soar through the sky. This was explained in Bernoullis Therom. more pressure on the bottom of the wing and less preasure on the top of the wings allowing airspeed.

What is drag?
Drag is created by anything that moves through air. Areo dynamics can help create less drag by cutting through the air smoother. It is very important to create less drag while flying so it is easy and more efficient to gain lift.

Describe the difference of air speed comparing the top of the wing to the bottom of the wing?
Bernoullis Law explains this, Airspeed on the top and bottom of the wings travel and allow air over and under the wings at different speeds. Under the wings less airspeed is made but more preasure is created to create more lift. While the top of the wing less preasure and more airspeed is made.

What is Form Drag?
Form drag is drag created from flaws from the aircraft design or any other drag created on the aircraft. Ex. Mirrors and Antenna etc.

How is drag reduced in some aircrafts?
Some aircrafts have winglets, winglets are folded wings that allow more stability in areas with low pressure.

What is center of gravity?
Center of gravity is pretty self explanatory. The center of gravity of the aircraft is the point and area of the aircraft where the aircraft is balenced equaly on all sides.

If a flight is in balance, describe how the four forces work together?
In flight when all forces work together the aircraft Flys unbothered by any force since the thrust and the drag equal out and the lift and Weight equal out.

What is the result of increasing thrust?
When one factor powers over the other three the whole aircraft is affected. Such as increasing thrust will affect the lift as altitude will be increase.

Penny Boat "Silver Yamato"

In the Second world War the Axis powers were I'm strong armament in the waters. The Germans with there u-boats and the Japanese with their largest Battleship known of the time. "The Yamato".

Tin Foil, Tape, and tooth picks cannot recreate the complexity of the Yamato. What was recreated was the idea. Since the Yamato was such a large ship which carried large cargo and armament we decided that it would be a great Idea to reuse the idea of the shape.(Note: May not look identicle)

132 Penny's later the Silver Yamato sunk the abyss of the sink. Leaving it in ruins.

Interm Report

So far in the semester I feel like I have done alright. Although with some exceptions of slacking I have pulled through.

When I come to class I am prepared to work and I come on time. My use of class time consists of constant work. Considering this I do get alot of downtime which I use as a break instead of trying to prepare for the next thing or to catch up if I'm missing anything.

I believe my work habits are much more successful with technology then on paper. Therefore I was 4 assignments behind. But 2 out of those 4 assignments were finished and handed in after finding out it was over due. IN GOOD QUALITY.

When I make blog posts or do an assignment on paper I am sure to always put my best foot forward on achieving good workhabit and good quality in what I do. Although we haven't done many projects this far into the course I would have to say the Memes. I say this because I thought it was fun to make a Meme in class time.

My plan for success is aiming for a B letter grade. My last year of science failed because I was lazy and didn't care about doing the work. But coming into this class I have a totally new mindset on what I want to achieve and what I need to achieve this goal of mine.

I strongly believe I deserve a "G" for a workhabit. For my constant effort in this class.

Traveling by Car

Taylor, Dilman, Dinuk and I are researching the time it would take to travel to Toronto. My part was researching how much time and money is spent and including convenince and Environmental impact.

If you were to drive to Toronto it would take you roughly 41 hours not including stops.  This route would travel through the U.S.

The cost of transportation will vary on what you drive. If you drive a hybrid of some sort gas will be very low in cost and adding on to that the gas in the U.S. Is much cheaper then here in Canada. If you took a very fuel efficient car the trip could only cost around the 100 dollar area and since it's very efficient you won't have to worry about environmental impact considering it won't use much fuel.

Ocean Acidification

What is ocean acidification?
Ocean Acidification is sort of like acid rain. In a sense. Pollution get taken into the atmosphere which gets transported to the ocean. The pollution turns the ocean acidic.

What human activities have caused this problem?
Since most energys are made by creating fire. Pollution is easy made. By using Cars. Machines and other types of items that create energy you are contributing to pollution.

How much has the acidity of the ocean changed?
The acidity of the ocean keeps increasing due to co2 emissions. 30 percent of acid has been increased since 2 centurys ago

How does the increased acidification affect animals in the ocean?
The acidification is ruining marine life populations which leads to the food chains being disrupted. Weight of plankton have decreased by 30 percent. And shellfish shells have been detiererating slowly.

How are pink salmon affected?
Petropods and dieing out. Just as explained above the food chain is being affected so the pink salmon are dieing out.

How are coral reefs affected?
Due to shells being destroyed by acidification coral reefs are being destroyed.

How might acidification affect you?
Food and resources will not be available if we use a careless attitude towards the ocean and our atmosphere in general.

What can you do to decrease co2 emissions?
Use more public transportation. Being more green.  Buy products that support the environment. Using less gas in anyway .
