(section: 2 / paragraph: e / line: 6)
Mass ratio answers should be entered to the number of significant digits allowed by the Event Supervisor.
(section: 3 / paragraph: a / line: 1)
For the class 1 lever the load point to effort point measurements must be less than or equal to 80.0 cm. The size of the the fulcrum is irrelevant to this measurement.
(section: 4 / paragraph: b / sub-paragraph: vii / line: 1-2)
The ratio should be presented as a decimal value, unless otherwise authorized by the Event Supervisor.
(section: 5 / paragraph: C / line: 1)
The way the ratio is recorded will be up to the local event supervisor.
(section: 3 / paragraph: a / line: 1-2)
Per 3.a. more than one mass may be impounded, but the total sum of all masses must be less than 3.5kg (Div C), 5.0kg (Div B)
(section: 3 / paragraph: a. / line: 1)
This is up to local event supervisors.
(section: 3 / paragraph: b / line: 1)
It can go through multiple conversions, but 100% of the energy must initially be gravitational potential energy.
(section: 3 / paragraph: b,c, / line: 1)
It can be stored and released, but 100% of the initial energy must come from the falling mass and event supervisors must be able to verify this. Also, all chambers must automatically return to ambient air pressure.
(section: 3 / paragraph: c / line: 1)
Yes, as long as the device remains safe and within other specs.
Yes. Competitors are permitted to force air back into the pressure chamber to return it to its initial shape and volume. The chamber must still be at ambient pressure at launch.
(section: 3 / paragraph: e / line: 1)
Yes, if the system is designed in such a way that were the second trigger not activated, other relevant rules are still met, such as rule 3.c regarding automatically returning to ambient air pressure and 4.c automatically returning to the launch area.
(section: 3 / paragraph: f / line: 1)
No, only the listed items in rule 3.f. are allowed as projectiles.
(section: 3 / paragraph: f / line: 1)
Teams must use only the type of balls listed with in rule 3.f.
(section: 3 / paragraph: h / line: 1)
Yes, as long as it is a removable tool that is not part of the device and removed prior to launch. The official SO laser policy must also be followed: http://soinc.org/lasers
No. General Rule #2 prohibits devices such as cell phone during the competition.
(section: 3f / paragraph: a / line: 3,4)
All the words "plastic", "practice", "golf", and "ball" must appear somewhere on the packaging or advertising description of the product, but not necessarily all in the same spot.
(section: 3f / paragraph: a / line: 3/4)
The most common type of plastic golf balls are plastic dimpled and plastic with holes and HDPE foam types are legal. As long as they are commercially marketed as "plastic practice golf balls", they may be used. It is recommended that students bring the packaging if there is a question.
(section: 4 / paragraph: a / line: 2)
Yes, the 1.5 m side of the launch area is the side that is parallel to the launch direction and the front of the launch area is 1 m wide.
(section: 4 / paragraph: e / line: 1)
Rule 4.d. explicitly says that the target is either tape on the floor or panels lying on the floor. There should not be any significant difference between the floor height in the launch area and the targets.
(section: 4 / paragraph: g / line: 1)
Competitors may choose either target for their first shot. They may then choose to take their second shot at the same target or their first shot at the other target. If they qualify to take a bucket shot after their first shot at a particular target, they must ask for the bucket when they wish to take the second shot at that target.
(section: 4 / paragraph: h / line: 2)
Competitors will be told the distance of the targets from the launch area and can measure their impact locations from the launch area if outside of the target.
(section: 4 / paragraph: i / line: 1)
Bucket distances can be arbitrary intervals.
(section: 4 / paragraph: i / line: 7)
Rule 4.i states that "making contact with the inside bottom surface is worth an additional 100 points." It does not state that after making contact the projectile must remain in the bucket, so the bonus is given even if the projectile subsequently bounces out of the bucket.
