Have you selected what you want to do for work someday? If not, this year might be a good time to start thinking about it, so you can prepare and utilize classes that GM offers to work towards that.

The most successful people are not the people with the most money, the most successful people are those that choose to work they enjoy.

 

Do not make the mistake, that just because you like something you will do it and make money doing it. Often these careers have lots of competition, and it will be up to you to put in the work to better yourself to stay competitive in these fields. If its an interest, get after it, be autonomous, Use the internet to learn more than whats being taught, continue learning through tutorials on YouTube, the learning doesn’t need to stop here. If you’ve created an extra something related to this class I’d love to see it!,  Thomas Edison once said “success is one-tenth inspiration and nine-tenths perspiration”

If you don’t have an idea yet, the best thing to do is to learn as much as you can about a variety of jobs or professions. Learn as much as you can about those that interest you. Find out what kind of secondary schooling it requires, what is the job outlook in 5 years? Does this career work with any of your special abilities?

Think about those things for the moment as we go around the room and introduce each other.

Introductions: what’s your name, grade, something interesting about yourself, is there a career in particular your interested in?

Interview

Intro to course: First week we plan to talk about rules and expectations as well as get to know each other by working on fun collaboration activities that require problem solving.

Classroom Rules

Class Itinerary 

Engineering is the application of scientific knowledge to solving problems in the real world. While science (physics, chemistry, biology, etc.) allows us to gain an understanding of the World and the Universe, Engineering enables this understanding to come to life through problem solving, designing and building things. So, problem solving, creativity, collaboration. All words synonymous with a good engineer, designer etc. So thats what this first week is about. Make no mistake, this course will certainly be about CADD, but the first week I’d like to begin with challenges that get you thinking like an engineering team. I have (5) of them either picked or designed for this class in particular. Click on the titles for links to the PDF’s or Google documents associated with collaboration projects below.

Save an Egg (45min)

*activity Egg Drop Challenge 

Ok, Class consider this scenario…

The International Space Station is a microgravity laboratory with an international crew of six people. Crew members spend different amounts of time living and working on the space station. When a crew member’s mission is over, the crew member returns to Earth to make room for a new crew member. Since November 2000, 222 people from 18 countries have visited the International Space Station!

As you can imagine. Transporting crew members back to Earth is not an easy task! One spacecraft that has been used to return crew members back to Earth is the Soyuz TMA spacecraft. The Soyuz can safely transport three crew members back to Earth.

Soft Landing Systems, a company involved in space travel, would like to design a spacecraft that is capable of transporting an entire crew (six people) back to Earth. Before designing a large-scale spacecraft and drop tower for testing, Soft Landing Systems wants to design and test prototypes of the drop tower and spacecraft capsule. By optimizing the prototype drop tower and capsule on a smaller scale prior to testing on a large scale, Soft Landing Systems will save valuable resources and money.

Soft Landing Systems has hired you as consultants on this project. They have asked you to work as a team of engineers to:

  • Design a prototype drop tower to drop the spacecraft capsule (simulating the return of the spacecraft to Earth)
  • Design a control circuit to hold the spacecraft at the top of the test tower until the start of the test (to prevent accidental drops that can be very costly with large-scale equipment)
  • Design a capsule to protect the spacecraftFor your prototype, Soft Landing Systems has requested that you use an egg to simulate the astronauts in the spacecraft. Your task will be to design the drop tower, control circuit system, and capsule to protect your spacecraft upon impact with the Earth.
  • You and your team will be given an assortment of loose end, non-related materials to create a way to drop and transport your egg starting at 4ft into a bucket with a goal of not damaging your egg.

Engineering Kahoot

 

Straw Bridge (100min)

The challenge is for groups (3-5 members each) to design and construct a model of a single-span bridge using plastic drinking straws and masking tape as the building materials. The bridge is to span a distance of 40 cm, or 1′ 3″ with no supporting pillars to the ground in between the ends of the span, is approximately 10 cm wide. It needs to be strong enough to support a suitable load. This might be a book, a can of food, or other object of suitable weight placed on the middle of the completed structure.

BINDER CLIP SHUTTLE  (100 min)

Principles of Flying. (1) Lift, (2) Gravity force or Weight, (3) Thrust, and (4) Drag. Lift and Drag are considered aerodynamics forces because they exist due to the movement of the Airplane through the Air.

Weight and lift

We all know that gravity is a force that pulls everything towards the Earth’s surface. This pull is called the weight force.

Planes and birds have to be able to provide enough lift force to oppose the weight force. Lift is a force that acts upwards against weight and is caused by the air moving over and under the wings. Flight is really like a constant tug of war between lift and weight.

Thrust and drag

The power source of a bird or plane provides the thrust. Thrust is the force that moves the object forward. Thrust is provided by:

  • muscles – for birds and other flying animals
  • engines – for flying machines, Jet engines, propellers.
  • gravity – for gliders that actually fly by always diving at a very shallow angle (birds do this too when they glide).

The force working against thrust is called drag. It is caused by air resistance and acts in the opposite direction to the motion. The amount of drag depends on the shape of the object, the density of the air and the speed of the object. Thrust can overcome or counteract the force of drag.

Have you ever stuck your hand out the window? When your hand is open facing forward there’s a noticeable amount of drag, but when lay your hand flat your hand is able to cut through the drag more efficiently.

Lift and Thrust need to complement each other to achieve flight.

 

Let’s investigate Thrust a bit further. According to Newton’s 3rd law, “For every action theres an equal and opposite reaction” what does this mean? Can you give an example?

If we were able to create transportation such as this, with supersonic transport, able move large amounts of goods and people over large spans what would this mean for our world?

Why can’t we just make planes with incredibly large jet engines?

What are the Common Skills Engineers Use?

Kahoot: Design & Engineering Process

Kahoot: Measuring 

Engineers are problem solvers, organizers, communicators, calculators and designers. These skills rely heavily on rational thinking and logical decision making, which is why most Engineers come from science and maths backgrounds. Yet despite this fact Engineering is a highly creative activity, especially when complicated problems are involved. The modern Engineer is also very software savvy and can use a range of different computing programs to assist in verifying designs and predicting how structures will behave in the environment.

What are the Common Fields of Engineering?

There are many branches and fields within the various Engineering disciplines which can be rather confusing. However, all Engineering degrees are based on one (or a combination) of the 4 major disciplines of CivilChemicalMechanical and Electrical Engineering.

Your project for careers is here. (2 days)

constraint: A restriction on the degree of freedom one has in providing a solution to problem or challenge.

engineering design loop: A specific and iterative set of steps that engineers use to evaluate and refine potential solutions to problems or challenges. The steps: identify the need, research the problem, develop possible solutions, select the most promising solution, construct a prototype, test and evaluate the prototype, communicate the design, and redesign. Also called the engineering design process.

iterative: Characterized by or involving repetition. The steps of the design loop are iterative (not rigid or linear). During the process, you may go back and forth among the steps and may not always follow them in order. For example, you may skip ahead to test a proof of concept or go backwards to learn more about the essential problem.

prosthetic: A device (external or implanted) that substitutes for or assists a missing or defective body part.

requirement: What a particular product or service should do. It is a statement that identifies a necessary attribute, capability, characteristic or quality. In engineering, sets of requirements are inputs into the design stages of product development.

target population: An identified population, clients or subjects intended to be served by a particular program.
