Boomilever - Div C

(section: 3 / paragraph: a / line: 1)

2014-01-23 15:55 3a says that the Boolilever must be attached to the mounting hook(s). If the attachment base on the boomilever has no hole but rests against the mounting hook does that count as "attached"?

Yes, the boomilever may rest against the mounting hook.

(section: 3 / paragraph: d / line: 1)

2013-11-30 07:48 Is it 5 cm below Contact depth of actual Boomilever being tested, or 5 cm from Contact Depth line?

Please refer to the posted Rules Clarification.

2013-11-30 07:55 Does rule 3d mean that the loading block must be at or above 5cm below the contact depth before start AND during loading? For example, can the loading block be at 25cm below the center line of the hook if the contact depth=20cm? Will this depth be...

The rule does not state that the loading block must be at of above 5cm below the contact depth during the loading. Testing will continue until failure of the Boomilever which is defined in 5.f.line 3.

2014-01-25 19:35 Can we use dowel joints to connect/join wood pieces in addition to adhesive? i.e. the dowel pins are made of wood.

Dowels are allowed as long as they are made of wood and meet the requirements of rule 3.g.

(section: 5 / paragraph: i / line: 2-3)

2014-03-27 19:41 What is the correct usage of the stabilization sticks (i.e. door stop end bumper only, wood dowel end only, either wood dowel or door stop end, or does not matter)?

To correctly use the stabilization sticks, the door stop end bumper should be used to touch the bucket, not the wood dowel end.

(section: 5 / paragraph: j / line: all)

2014-01-23 15:52 Please explain "Failure." Should loading stop if a piece breaks off the structure? Rule 3.a. states that it must be a single structure.

Failure is defined specifically in rule 5.j. Rule 3.a. defines the construction parameters of the structure, not what happens to the structure during loading. Therefore, if a piece breaks off the structure during loading and the structure is still supporting the load, loading will continue until failure occurs as defined in 5.j.

2014-01-27 02:02 Are lasers allowed?

No, lasers are not allowed. They are not one of the listed legal components in rule 3.i.

(section: 3 / paragraph: a / line: 1)

2014-03-12 00:44 If the device is contained within an actual cube and attached to portions of the walls and floor, will the measurement of the device include all of the structure (walls, floor, etc.) or just the portion of walls and floor used within the cube?

The measurements will be for the entire space the device takes up including the walls, floor, and any part of the device that might extend beyond these boundaries during the running of the device. Hence, during the running of the device if anything extended (even temporarily) beyond the stationary boundary the event supervisor will need to remeasure the device.

(section: 3 / paragraph: e / line: 1)

2014-03-12 00:19 What constitutes an energy transfer?

If energy is converted it is surely transferred. It can also be transferred without being converted. Energy triggers can count for points. The initial energy can trigger something to cause the next energy to release and it does NOT have to be converted to the final energy for it to count for points.

(section: 3 / paragraph: e / line: 2)

2014-01-25 19:30 May batteries receive points based on a chemical to electrical energy transfer?

No, because batteries must be factory sealed, thus there is no action you can perform to initiate the chemical energy input to the transfer and per Rule 3.g. "All scoreable actions and transfers must be visible...."

(section: 3 / paragraph: f / line: 1)

2014-03-12 22:30 3.f. allows previously used motors to be switched off. Can other previously used circuits be switched off, example, a hot nichrome wire?

Yes, as long as two actions do not contribute to the task sequence at the same time.

(section: 3 / paragraph: g / line: 1-2)

2014-03-12 22:34 Do the steps need to be visible DURING operation, or just able to be made visible to show a judge?

The rules do not say the every task must be visible to the judges during operation, but tasks need to be verifiable by a judge. If they cannot completely verify a task actually took place, then it might not be counted for points.

(section: 3 / paragraph: i / line: 1)

2014-02-11 16:03 Now that all electric components are allowed, can we use lasers?

No, Lasers are not allowed in the devices per the Science Olympiad Laser policy found on the website The first sentence of the policy rules them out for Mission Possible, "Laser levels, pointers and other laser devices are intended to be operated under the control of a human operator at all times."

(section: 3 / paragraph: j / line: 1)

2014-01-25 20:08 Does a wing nut on a threaded rod or a string on an axle rotated by a motor count as a continuous electrical action designed to take up time, even if the action is mainly mechanical, only powered by an electrical source?

Yes, these are considered a continuous electrical action intended to take up time and is not legal.

(section: 3 / paragraph: m / line: 1)

2014-01-26 22:41 Rule 3m. states that "All batteries must be factory-sealed and voltage labeled by the manufacturer." Does this mean that (non-hazardous) home-made batteries like lemon batteries are not permitted?

Correct, any type of homemade batteries are not allowed per rule 3.m. A battery is defined as a device that utilizes a chemical reaction to generate voltage and current.  Note that chemical reactions that result in a change in resistance are allowable in devices.

2013-11-04 02:12 Does the final task have to be an electric lightbulb?

No, but some sort of light must be switched on per rule 4.g.

(section: 4 / line: a)

2014-01-25 20:54 Who chooses what items are used for the start task and how many of each item, the event supervisor or the team members?

The team members choose what items are used and how many of each item for the Start Task.

(section: 4 / paragraph: a / line: 1)

2013-11-01 02:05 Are the objects in the start task provided by the teams or the event supervisor?

Each team brings their own items for the Start Task.

2013-11-04 02:08 What is the minimum number of golf tees, paper clips, & marbles allowed in the mixture? Would it be acceptable to use 0 of one of the items?

A mixture is an aggregate of 2 or more different substances therefore teams may use only 2 of the 3 items in their mixture.

(section: 4 / paragraph: F / line: 1 & 2 )

2014-01-27 04:04 What constitutes a "container"?

A container by definition must be capable of holding, restraining, and containing its contents (i.e. golf tees, paper clips, and/or marbles) in the container's volume or area. Containers may have modifications as long as they meet the definition of a container and comply with the rules. While the containers do not have to be removable from the device, a key test would be the question, "if the container was moved outside of the device, would the contents remain in the container?"

2014-02-13 14:42 Are ramps allowed this year assuming the egg starts at the starting line?

No. Vehicles are not allowed to start on ramps and the vehicle cannot be the falling mass. If the wheels are not touching the floor in the “ready to run” configuration then they would not be allowed to touch the floor after the run has begun since it would be in violation of the rules (see FAQ posted on 12/22/13).

(section: 2 / paragraph: H / line: 1)

2013-12-23 02:07 This section of the rules states that only the wheels of the scrambler can make contact with the floor. Does this mean that the falling mass can't make contact with the floor?

Only the wheels of the Scrambler and any parts of the Scrambler in contact with the floor at the ready to run configuration are allowed to contact the floor. If any piece falls off the Scrambler during the run, it is a construction violation. Therefore the falling mass cannot touch the ground at any time.

(section: 3 / paragraph: b / line: 1)

2014-02-28 17:22 It is not stated in 3.b. but I assume the actual starting line is the front edge of the 1in. tape (closest to the terminal barrier) and is the same for the .2m & 8.2m lines with the inside edge of the track tape defining the Track width.

Yes and no. The tape for the start line - correct. The other tapes are really up to the event supervisor as long as timing begins exactly 0.2 m from the start line and ends 8.2 m away from the start line. The Event Supervisor will let the team members know which edge of the tape correspond to each of the lines specified in the rules. Finally, yes the inside edge of the side tape should defined the track width.

(section: 3 / paragraph: f / line: 1)

2014-03-10 02:11 Does a 1/4" x 1/4" piece of balsa qualify as a 'dowel'?

No, a dowel by definition is a solid cylindrical rod.

2014-03-14 01:53 Is plywood considered to have pre-glued joints and therefore not allowed for construction?

Plywood is not considered to have pre-glued joints, it is legal for use.

(section: 3 / paragraph: c / line: 2)

2014-01-02 00:56 May any type of thread that is conventionally used in sewing garments be used to attach the functional components of the glider to each other, namely, cotton thread, polyester thread, elastic thread and silk thread?

Yes, any type of thread may be used to attache the functional components.

(section: 3 / paragraph: d / line: 1)

2014-01-02 03:06 Is ballast that is not permanently attached to the glider allowed in order to bring an individual glider up to the 3.0g minimum weight?

Yes. If ballast falls off during the flight, timing will stop when the ballast touches the ground. Ballast does not need to be permanently attached. If the event supervisor feels ballast changes, repairs, or other modifications have potentially made the glider over or underweight, the glider should be reconfirmed prior to any remaining flights.

(section: 3 / paragraph: e / line: 1)

2014-01-02 01:14 How will the wing-span be measured?

Wing span is the projected span, wings level, projected on a horizontal plane, tip to tip. It is usually measured with a simple gage and has to pass through a 28.0 cm gap (parallel edges) without touching. Think of the gage as physically representing two parallel lines spaced 28 cm apart. Glider must pass when the tips are oriented to a plane orthogonal to both lines.

(section: 3 / paragraph: f / line: 1,2)

2014-01-02 01:11 May the gliders have a propeller on the nose of the fuselage?

Yes, A glider may have a propeller as long as there is no power source for the propeller, provided it is made from the allowed materials (3.c.), and meets the blunt nose requirement (3.f.) Also, remember elastic is only permitted as part of the launch handle and is not permitted on the glider.

(section: 3 / paragraph: g / line: 1)

2014-01-02 01:23 Can you specify what do you mean by launch handle?

A launch handle is an object attached to the elastic used to propel the glider as long as it follows the parameters defined in the rules. Examples are, but not limited to: a small stick, pencil, pen, dowel, or something more complex.

(section: 4 / paragraph: b / line: 1)

2014-01-02 01:30 Rule 4.b. states, “Once competitors enter the cordoned-off competition area to trim, practice, or compete they must ....not receive outside assistance, materials, or communication.” Does this apply to open practice the day of competition?

Yes, this rule applies to Open Practice the day of competition. The rule is specific including trimming, practicing and competing. Coaches & students are not allowed to interact in the cordoned off practice area the day of the competition.

(section: 4 / paragraph: g / line: 1)

2014-01-02 01:31 Can a launch handle/device be a freestanding structure in contact with the floor?

Yes provided it is safe and meets the size and construction requirements (3g.) and is operated by a single competitor at floor level (4g.)

2014-01-02 01:34 Can you clarify what "floor level" means?

The student must be in direct contact with the floor and not on another raised suface (chair, ladder, bleachers, balcony, etc). There is mo requirement as to posture: standing, kneeling, sitting, prone at chose of the competitor.

(section: 4 / paragraph: k / line: 2)

2014-03-09 18:56 Is your hand holding the elastic allowable as a launch handle?

Yes, your hand holding the elastic may be the launch handle.

(section: 5 / paragraph: b / line: 1)

2014-01-02 01:38 What are the exact specifications needed for a glider to be considered a Canard Configuration?

There are two horizontal aerodynamic surfaces in elastic launch gliders. The larger surface is the primary source of lift and is considered the "wing." The smaller is a stabilization source and is considered the "horizontal stabilizer." Canard configurations place the horizontal stabilizer in front of the wing (reverse that of traditional layouts.) No aerodynamic surfaces may be behind the main wing.

2014-01-02 01:56 Does a "canard configuration" refer only to the horizontal surface, i.e. can there be a vertical fin at the rear of the glider?

Yes, a vertical fin may be at the rear of the glider for a canard as long as it does not provide any lift.

2014-03-11 23:26 For the official flights if we fly both a canard and a non-canard glider, how would the total score computed? Alternatively, to compute the longest flight time would you consider 30% bonus for Canards?

Each flight will be scored and the bonus (if applicable applied) to that flight. The top 3 flights will then be added to compute the total score.
