This is a course that helps students understand the field of engineering/engineering technology. Exploring various technology systems and manufacturing processes help students learn how engineers and technicians use math, science and technology in an engineering problem solving process to benefit people. The course also includes concerns about social and political consequences of technological change. |

UNIT 1 - Definitions and Types of Engineering Engineering fields, as with most other fields, offers opportunities for all types of personalities and interests. Those who enjoy working on computers to examine complex problems can be designers; those who like to work with their hands can be involved with manufacturing; those with strong people skills can move into management, sales, or customer support; those who want to be involved in helping people directly can work side by side with doctors to develop major new technologies.

Week of 9/20: SIMPLE MACHINES A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use Mechanical Advantage (also called leverage) to multiply force. A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load. The ratio of the output to the input force is called the mechanical advantage. Safety First
- Safety Statements and Safety Test:
SMET˛ (Using Science, Math, Engineering, and Technology to create a Simple Machine Energy Transformation Device) In teams of two, students will use their knowledge of simple machines to design, construct and test sections of a device which will transfer energy from the first section to the last without human intervention. |
HOMEWORK:
WATCH: SIMPLE MACHINES POWERPOINT #1 SIMPLE MACHINES POWERPOINT #2 READ: Mechanical Advantage and Simple Machines THEN COMPLETE Simple Machines Practice Problems Due: Tuesday, September 27 SMET˛ 2011 SCHEDULE:
First fitting:
OCTOBER 11. Your SMET section does not
have to be working yet, but its exit point and the entry point of the
two bordering sections must be lined up. FINAL RUN (GRADED) WILL BE DURING SECOND HALF OF PERIOD ON OCTOBER 21st. Engineer's Report: October 24th. |

HAVE YOU LOST YOUR MARBLES?? Today’s consumer pays a steep price (both long
and short term) for products made from virgin materials. Most often,
these products find their final resting-place in the local landfill. As
a post-industrial society, we have a need as well as a responsibility
to view our used products as a resource; to reuse, remanufacture, or
recycle these products back into the manufacturing cycle. As recycling
centers become a more common sight in our community, we must try to make
them as efficient and cost effective as possible. Sorting the various
components of trash is a time consuming process. Any effort made at
trying to automate this task would increase the cost effectiveness of
this operation. |
When you begin to write your program, get a pencil/pen and a piece of paper WRITE them, in words, BEFORE YOU TRY TO WRITE THE PROGRAM IN THE COMPUTER!!!! What do you want to happen when, and how is it going to happen? When you do begin to program, remember to ANNOTATE your programs as you write them, and when you get ready to print, make sure it is large enough that it can be read.

Employability refers to a person's capability of gaining initial employment, maintaining employment, and obtaining new employment if required (Hillage and Pollard, 1998). In simple terms, employability is about being capable of getting and keeping fulfilling work. Graduation is on the horizon... you are probably going to want to get a position with a good company very soon. This unit will help you get there! After the video, go to your S: Drive. Open the 905 POE folder and then open the Resumes folder. Open the document, "The Most Important Feature of Your Resume". Read this document. There will be questions you will have to answer when you are finished. |

| APRIL 16 - MAY 4TH:We will begin Unit 5: Statics & Strength of Materials. Students will construct a virtual truss bridge in a software called MDSolids, then construct the real thing using "tagboard" (file folders) to demonstrate stresses. CLICK HERE for Bridge requirements. Bridges will be tested May 2nd, and Engineer's Reports will be due on May 4th. |
The following links will aide you in completing your Bridge: Link to
Learning Activities Manual
BUILDING BIG: Forces Lab **Keep in mind that you are building your bridge to achieve the greatest STRENGTH-TO-WEIGHT RATIO. The strength-to-weight ratio is a measure of the efficiency of a structure - normally associated with things like bridges. It compares the weight of the structure itself to the amount of weight it can carry/support without collapsing. For example the miniature file-folder or wood-stick bridges you build at school will have a very high strength to weight ratio; in the hundreds, sometimes the thousands. This is because they weigh only a couple dozen grams, yet are able in some instances to hold one or two hundred kilograms without breaking! A modern-day metal bridge however will have a strength to weight ratio nearer to 1. |
UNOFFICIAL RECORD HOLDER: Congratulations to
2008 Winner,
William Walters, whose bridge held a whopping 283.0111 lbs.
(128,273 g) and still did not break (we ran out of weights!) His
bridge's known Strength to Weight Ratio of 367 : 1,
however, it was not built to specifications, therefore, is not in the
record books.
