Does the tower need to hold the bucket to earn the bonus?

Does the tower need to hold the bucket to earn the bonus?

ceann Thu, 2018-02-08 12:31
Yes, the tower must hold the bucket to earn the bonus. Teams will not receive the Load Score Bonus (6.c.) if their Tower breaks prior to loading sand which is defined as sand being added to the bucket either by pulling the lever of the hopper or the participants attempting to pour sand into the bucket. These teams will have the mass of the Loading Block Assembly used as their Load Score (6.b.) for the purposes of determining the final event score (6.a.).

If a tower fails when the loading block assembly is placed (and the tower meets all dimensional and other requirements), does the tower receive the minimum mass (the Loading Block Assembly) and/or are they subject to tier 2-4?

If a tower fails when the loading block assembly is placed (and the tower meets all dimensional and other requirements), does the tower receive the minimum mass (the Loading Block Assembly) and/or are they subject to tier 2-4?

ceann Thu, 2018-02-08 12:38
The minimum load scored is that of the Loading Block Assembly (6.b, 5.b). So if a tower cannot support the Loading Block Assembly it must be scored in Tier 4; unable to be loaded. If the tower supports only the Loading Block Assembly, then the tower is scored in the appropriate tier (1, 2, 3) and the weight of the Loading Block Assembly is scored.

Does rule 3i imply that any electrical device which operates for more than ten seconds would be a construction violation?

Does rule 3i imply that any electrical device which operates for more than ten seconds would be a construction violation?

ceann Mon, 2018-01-01 21:01
Any type of electrical or spring action that operates for more than 10 seconds and still controls part of the action would be a violation. If a light bulb, fan, etc. remained on but was no longer used or no longer affected the device in any way to contribute to points it could be allowed to stay on without penalty.

If the expanded gas in 4.b.xi inflated the balloon in 4.b.i, does that count as two scorable actions?

If the expanded gas in 4.b.xi inflated the balloon in 4.b.i, does that count as two scorable actions?

ceann Tue, 2017-12-12 21:34
No, an action may count for only 1 Scorable Action at a time.

May a single battery source whose total output does not exceed 14.4 volts as labeled be used for more than one action and receive the bonus points for 1 battery source?

May a single battery source whose total output does not exceed 14.4 volts as labeled be used for more than one action and receive the bonus points for 1 battery source?

ceann Tue, 2017-11-14 20:01
Yes, because a single battery source is not “moveable/adjustable” it may be used for more than one action as long as it complies with all other rules and if it is the only battery source in the device the team will receive 100 points.

May the "next task" started by the timer be the final action (4c)?

May we use sealed lead acid batteries?

May we use sealed lead acid batteries?

ceann Tue, 2017-11-14 19:45
No. Sealed lead acid batteries are not allowed. They could be considered considered hazardous material per Rule 2.d.

The rule states: Add Water to a closed container so that it completes an electric circuit and begins the next action. What does "it" refer to - the water or the closed container?

ceann Tue, 2017-11-14 12:31
The word “it” refers to the water. The addition of the water to the container must complete an electric circuit which begins the next action.

What defines a "closed container? Would it be need to be completely sealed or just enclosed to prevent spills?

What defines a "closed container? Would it be need to be completely sealed or just enclosed to prevent spills?

ceann Mon, 2017-10-23 18:59
The container must be closed but does not have to be air tight. When water is added to the container, any liquids and/or solids must stay within the closed container and no one can be physically exposed to them.

What differentiates a chemical from a mechanical task (in reference to a timing mechanism)?

What differentiates a chemical from a mechanical task (in reference to a timing mechanism)?

ceann Tue, 2017-11-14 12:46
For timing purposes, If a chemical reaction causes a mechanical action, once the mechanical action initiates the next action, no more chemical timing points can be earned even if the reaction continues.

What is considered a "controlled" flame?

What is considered a "controlled" flame?

ceann Thu, 2017-11-02 20:03
For the purposes of Mission Possible, a “controlled” flame is one in which the fuel source for the flame is limited so that the produced is kept as small as possible but still capable of carrying out the required action. The flame should be shielded from the rest of the device so that it only impacts upon the intended target so that it completes the specified task and does not provide a fire hazard to the rest of the device. Furthermore, the flame should burn out quickly, not produce any additional flames, and produce a limited amount of smoke. Participants are reminded that the Mission Possible event will be held indoors in room equipped with smoke detectors and it is the expectation that a Mission Possible device does NOT set them off. Event supervisors are encouraged to conduct a safety pre-check of all devices to make sure that no identifiable safety hazards are present. Fuel sources such as flammable liquids or gases, chemicals such as magnesium ribbon, and compounds such as gunpowder are unsafe and should not be permitted in a device. If the event supervisor has any doubt they are encouraged to err on the side of caution.

What is defined as "water"? Saltwater?

What is defined as "water"? Saltwater?

ceann Mon, 2017-10-23 19:22
Water is defined as, "a transparent, odorless, tasteless liquid, compound of hydrogen and oxygen, H 2 O." Salt water would not qualify as water being added into the container.

Will teams be allowed to use microcontrollers, arduinos, integrated circuits, etc.?

Will teams be allowed to use microcontrollers, arduinos, integrated circuits, etc.?

ceann Tue, 2017-11-14 19:43
Yes, but they can only activate one action and must comply with all the rules including taking no more than 10 seconds to activate an action. They may not be used to control multiple actions. They are considered an adjustable object therefore are only allowed in one transfer per microcontroller, Arduino, integrated circuit, etc.

Would turning off an electric motor (in order to comply with the 10 second limit), be considered a "dead-end action?"

Would turning off an electric motor (in order to comply with the 10 second limit), be considered a "dead-end action?"

ceann Tue, 2017-11-14 10:55
If the motor is turned off just to do that and not to score any additional points, then it would be allowed. If a team tries to gain more points by this action, then it would not be allowed.

Can the vehicle use energy from one (or both) of its mousetraps to "launch" the cup across the Cup Target Line (with the cup in contact with the floor) instead of moving the complete distance to push the cup across the line?

Can the vehicle use energy from one (or both) of its mousetraps to "launch" the cup across the Cup Target Line (with the cup in contact with the floor) instead of moving the complete distance to push the cup across the line?

ceann Wed, 2018-03-28 19:53
No, "launching" the cup with the mousetrap(s) would be a violation of rule #1. The vehicle must be designed to push a plastic cup forward, not launch the plastic cup forward. The mousetraps are to be used for propulsion. The vehicle must also be designed to move forward and then reverse direction, stopping behind the start point.

What is meant by "a calculator dedicated to computation" and are there specific calculator models that are allowed?

What is meant by "a calculator dedicated to computation" and are there specific calculator models that are allowed?

ceann Tue, 2017-10-17 14:46
The phrase “…a calculator dedicated to computation…” refers to a standalone or dedicated calculator. With these calculators their functionality is limited to mathematical calculations or associated activities such as running simple computational programs or producing graphs. This means that digital or electronic calculators such as those found as an application on a computer, tablet, watch, or cellular phone are not permitted for use in Science Olympiad events. In some events there are no limits to the functionality that the calculator may possess. In other events, the calculators may not have features that allow them to run programs or create graphs. With the ever-changing landscape around calculators and other personal electronic devices Science Olympiad is not in the position to be able to review and permission specific calculator manufacturers or specific calculator models. In every case, the decisions of the Event Supervisors concerning the acceptability of a specific calculator type for an event at a tournament shall be considered final.
