2 The challenge Build a crane able to lift a load from the floor using mechanical potential energy. Participate in Science, on tourne! Professional category Eligibility: Any student youth or adult enrolled at a public or private college in Québec in a full-time or part-time program in any discipline regardless of whether the program is offered through regular or continuing education. Amateur category Eligibility: Any staff member employed at any public or private college in Québec. How to sign up Create your team (no more than 3 participants per team). Each competitor must sign up at his or her own institution. The team members must be the same for the local and national finals. Contact the student services office to get the name of the person in charge of the contest at your college (the local organiser). Complete the registration form given to you by the local organiser and return it to him or her. Attend the information meeting that will be held at your college. Each participating team must give its gadget an original name. Trademarks and registered marks may not be used. The same name must be used for both the local and national finals.

3 There are many prizes to be won, including two trips to James Bay, a travel bursary to participate in the Sciences et Citoyens event in France, and subscriptions to Québec Science as well as thousands of dollars in cash prizes and academic bursaries, etc. good Luck! Local finals From January 17 to April 12, 2013 Each institution organises its own local finals during which teams compete in their respective categories (Professional or Amateur). Each college is responsible for forming the jury that will evaluate the performance of the teams competing in the local contest. Each participating college can award prizes to the winners of the local finals in the Professional and Amateur categories. It is up to the college to decide what those prizes will be. The winning team at each college will be invited to participate in the national finals (one team per college per category). The names of the winners of the local finals must be sent no later than April 12, 2013 to Ludivine Ollive by to lollive@cegepgarneau.ca. National finals May 4, 2013 at the Cégep de l Abitibi-Témiscamingue The national finals bring together the winners in the Professional category from each college. The public is invited to attend the event. The Amateur category winners will get together for a friendly evening competition at the same venue the evening before on Friday, May 3, The Science, on tourne! steering committee is responsible for forming the jury for the contest s national finals. The jury s decisions are final and without appeal.

4 The great hoist The challenge Build a crane able to lift a load from the floor using mechanical potential energy. To successfully meet this challenge, your crane will have to raise a load to a given height and hold it there for at least 3 seconds. To obtain the highest possible score, you will have to achieve an optimal load-crane ratio. The M multiplier also serves to raise your score. It s up to you to try and meet the challenge!

5 COUNTERWEIGHT A ,1 floor detail DÉTAIL A a load weight Scoring P = crane weight x M Where (M) equals 1,000, 2,000, 4,000 or 8,000. Here are the conditions that serve to determine the value of the M multiplier: (C1) The crane places the load entirely within the volume of the depot area and the load remains inside this volume for at least 3 seconds. (C2) The crane is located entirely above the level of the top surface of the plywood sheet before being started. If none of these conditions is met, then M =1,000. If only condition (C1) is met, then M = 2,000. If only condition (C2) is met, then M = 4,000. If both conditions (C1) and (C2) are met, then M = 8,000. There will be two rounds in the competition: a qualifying round at the end of which the four best teams will go on to participate in the final round. To determine the ultimate winner of the competition, the result obtained for the qualifying round will be added to one quarter of the result obtained for the final round. In the event of a tie, the team with the lightest crane during the final round will win. The weights of the load and crane will be determined by a scale that weighs in grams. The score will be rounded to the nearest unit. DeFINITIONS Load: The object that will be made by the team and which must be raised by the crane. Crane: The device consisting of anything that is neither the load nor the playing area and which is used to meet the challenge.

6 table plywood Tie-Down area depot area X 0.77 ALL A TRAVERS THE WAY TOUT THROUGH 25 Playing area 48,00 121,9 50 The playing area consists of a table, a sheet of plywood, a counterweight, and the floor. 1.1 A folding table (30 inches wide by 72 inches long) supports the sheet of plywood. 1.2 The sheet of plywood (¾ inch, good two sides) measures 50.5 cm X cm (4 feet) and it is placed cantilever style (overhanging the edge) on the table. Its upper surface must be 80.0 cm from the floor. This height can be adjusted by placing shims under the feet of the table. The plywood sheet features two zones: the tie-down area and the depot area. a. The tie-down area is a surface that measures 25.0 cm x 25.0 cm, and holds four threaded 3.1-cm bolts (¼ 20 x 2 in. long). Four butterfly nuts will be provided if needed. b. The depot area is a volume that measures 25.0 cm x 25.0 cm x 90.0 cm. This is the place where the crane has to place the load in order to meet condition (C1). These areas are marked off by two strips of black ¾-inch adhesive tape. One of these strips is 50.0 cm long; it separates the two areas from the rest of the sheet of plywood and is located inside these areas. The other strip is 25.0 cm long and is placed between the two areas to separate them. It is positioned inside the depot area. 1.3 The counterweight has a mass of 1000 g. It consists of a capped soft drink bottle containing the appropriate volume of water. It stands on the sheet of plywood as indicated in the drawing. 1.4 All dimensions are precise to ± one millimetre.

Rules A team can be barred from participation in the contest or disqualified if it fails to comply with one or more of the following rules: 2.1 The only permitted source of energy is mechanical potential energy. 2.2 The crane and load must have been made by the members of the team. 2.3 The weight of the load on the scale must be less than or equal to 2000 g. 2.4 No part of the crane or load may be higher than 90.0 cm above the sheet of plywood at any time (except during the final round). 2.5 Prior to performing the start-up action, after the team has informed the referee that is ready, the following conditions must be met: a. Any contact between the playing area and the crane must occur only within the tie-down area. b. The load must not extend higher than 10.0 cm from the floor. c. The load cannot be placed under the table. d. The load must be in contact with the floor. e. Only the load can be in contact with the floor. f. The load may not contain any energy other than its own potential gravitational energy. g. Any mechanical potential energy (except for that permitted by item f) must be stored in the crane. h. The team may no longer touch either the crane or the load. 2.6 The crane must be started up in a single action and using only one hand. A tool may be used. 2.7 The energy provided by the start-up action must neither influence nor improve the crane s performance. 2.8 Apr a. b. c. d. e. 2.9 Apr a. b Le f auc jeu 2.11 La g doiv de 5 dim Les organ relatives autant qu de la fina responsa finales lo

The load must be raised above the upper surface of the plywood sheet for at least three seconds in order for the team to qualify for scoring. 2.9 After the official trial: a. The plywood sheet must lie only on the table. b. It must be possible to determine the individual weights of the crane and the load easily with minimal handling The crane, its components and their operation must not pose any danger to people nor be likely to damage the playing area or the competition premises The crane, load, tools and the rest of the technical material must fit into no more than 2 separate boxes that would normally each hold 5,000 sheets of letter-sized paper (21.6 cm by 27.9 cm / 8.5 X 11 ). The boxes when closed must have their original dimensions. The conditions governing the national finals can be adapted by the organisers of the local finals. However, we recommend you comply as closely as possible with the rules that will be applied during the national finals. The Science, on tourne! steering committee is not responsible for any rule changes made for local finals.

9 National Finals Before the competition 3.1 On the evening of Friday, May 3, 2013, each participating team whether competing in the Professional or Amateur category must have the crane and load it has built verified. 3.2 Each team will have to explain how its crane works, show that the only energy source used is potential mechanical energy and that their entire set-up is safe (see Rule 2.10). During the competition 4.1 When invited to do so by the competition presenter, the team places its material in the presentation area in the foreground. 4.2 The team has two minutes to give its oral presentation. 4.3 When the referee blows the whistle, the team has four minutes and thirty seconds to: a. Set up its crane in the tie-down area; b. Perform one or more non-official trials if it feels the need to do so; c. Place the load where it needs to be on the floor; d. Signal to the referee that the load is ready to be verified (see rules 2.5.b to 2.5.f). The timing device is stopped while the load is being verified. Once the load has been verified the timing device is started again; e. Attach the load to the crane, if necessary; l exception du marche (le ch la mise en march les 60 secondes d C est à ce momen grue effectue l ac grue et la charge f. Se retirer der g.

The entire team, except for the person who is to perform the startup action, moves to behind the withdrawal line with the rest of the material; g. Inform the referee that the team is ready to perform the start-up action (the timing device is stopped during this time). 4.4 The referees make sure the playing area meets the rules before the start-up action is performed. The timing device is set to zero. 4.5 At the referee s signal, the timing device is started again to time the sixty seconds the crane has to complete the official trial. At the same time, the team member who remained near the crane performs the start-up action. 4.6 If the start-up action is unsuccessful, it can be repeated. 4.7 After the trial is over, the competition officials weigh the crane and load separately to determine the score. The final round The four finalist teams play against one another during the final round to determine the winning team. They will compete this time on a modified playing area. The upper surface of the plywood sheet will be raised from 80.0 cm to 88.0 cm from the floor. Rule 2.4 will be modified and will now read: No part of the crane or load may be higher than cm above the sheet of plywood at any time.
