=Egg Drop=


 * Learning Objective:** You will be exploring the world of forces and materials. You will be dealing with a moving object and the effect of gravity and speed. Design engineers must make their products stand up to use and abuse. Industrial engineers design packaging to hold new products until, and sometimes after, they are purchased. In both cases the engineers utilize their understanding of forces, gravity, speed, acceleration, inertia, statics and dynamics, materials and ergonomics to create sturdy, practical and safe designs. To make sure they’ve got it right they test and re-test their products. These tests are designed to simulate situations that the product will be found in.

For 3 keywords and research and list the uses for: energy absorbing materials, g-forces, inertia, Newton’s laws, impact absorbing metals, packaging.


 * Challenge**: To successfully transport a Canadian Large Grade A egg, from a height of 426.72 cm (14 feet). The landing pad will be concrete, 24 inches squares. The egg must not be broken. You’ll need to protect it. The weight of the apparatus should be no more than 400 grams (but there is some flexibility in that respect). All construction materials MUST be food products. Each individual will, in addition to whatever food they bring in to build the delivery vehicle, be given 1 sheet of plain white paper and may use wood glue as adhesive for said piece of paper.


 * Supplied Materials**: 1 egg

1. Upon impact, the egg must remain intact. 2. Container must be made out of food with an optional inclusion of the piece of paper given to them. 3. The container can be any shape. 4. The egg will be dropped from a mechanical hook system (robotic hand that opens) 5. No use of lines (to control the direction or speed) – once it’s free from the hook it can have no contact with people or any manipulated part of the environment. 6. Nothing can be adhered to the egg itself. 7. You will be given the egg you will need to use on the test day (Unless special preparations are necessary and discussed with the instructor //**ahead of time**//) 8. NO hard-boiled eggs allowed.
 * Rules and regulation**:

• Before construction begins – sketches must be given to a colleague. After completion, a final sketches are to be submitted with the design report. The drawings will include all relevant details as pullouts. • Packaging construction - overall design of the finished product will be evaluated including: dimensions, style and adherence to the working drawings. All sizes greater than 8"x8"x8" will be penalized by 1 mark per 1/2". • Performance results - (4) indicates egg remains completely safe, no visible rupture of the shell, (3) indicates one or two small cracks may be present, but the products isn't leaking, (2) product is leaking, and shell cracked, but not badly so, (1) product is broken • Self-Evaluation/ write-up.

 * **<span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Sketches ** || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">sketches are flawless - pullouts (notes) include relevant design details || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">sketches are good, pullouts are included. Mostly all details are addressed. || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Generally the sketches conveys design plans. There are several design elements missing. || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Many design elements are missing from the sketches, but overall the design can be understood. ||

<span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;"> **<span style="font-family: &#39;Arial&#39;,&#39;sans-serif&#39;;">(double value) ** || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Construction of the product is superior. All joinery and cuts are careful and deliberate. Product is stylistically superior. || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Construction is sound. Cuts and joints may not all be perfect. Product is generally pleasant to look at. || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">Generally the construction is solid. Cuts and joints as well as style all leave something to be desired. || <span style="color: #000000; font-family: &#39;Arial&#39;,&#39;sans-serif&#39;; font-size: 12px;">The construction is weak. Joints and or cuts are mismatched which results in a stylistically inferior product. ||
