FRC Bowling Ball Competition Questions
Q: According to the specifications for the bowling ball competition, a core-filled ball is allowed. But I have a hard time fully understanding the meaning of "core-filled." Does it mean a solid sphere or a hollow sphere? Or can it also be a hollow sphere with additional solid sphere inside of it as the "core-filled" part of the ball?
A: Core-filled means that the center (core) of the bowling ball may be filled with a non-concrete substance. See rules about Non-FRC materials.
Q: When the balls are tested, should the balls be at their 28th day?
A: There is no rule regarding this.
Q: Since there is no requirement about the concrete age in the Rules, can we cast the concrete as early as possible to gain a bigger strength?
A: No comment, meaning that is not the rule makers' decision and again there is no rule regarding this.
Please clarify the above.
The clarification is that the normal interpretation of contest rules is that unless something is said, there is no rule or constraint on what is done. Another way to say this is permission is given to do whatever unless the rules say what to do or what not to do.
Q: Is the bowling ramp fixed? Could the team bowler modify the direction or the position of the ramp?
A: Repositioning of the ramp has not been decided by the judges (see … regarding the judges' authority to change/modify/interpret the rules)
Q: What is the format and size of the testing apparatus' plates?
A: Hardened steel plates 6.5 in. (165 mm) in diameter (this is a different machine from the previous contests and see … regarding the judges' authority to change format and size)
Q: Our team noticed that the "earliest pour" date has been removed from the rules. Can you confirm that the FRC Bowling Balls can cure for an unlimited amount of time?
A. The normal interpretation of contest rules is that unless something is said, there is no rule or constraint on what is done. Another way to say this, permission is given to do whatever unless the rules say what to do or what not to do.
As a result of all this, we make no comment on the specific question other than the underline above.
Q: The bowling balls shall be spherical (no finger holes) and measure 200 mm ± 15 mm diameter. Do you mean no hole on the ball? or free hole size and diameter?
A: A normal bowling ball has three finger holes for the bowler to handle and control the bowling ball throw and resulting roll down the alley. The bowling balls for this competition have no need and will NOT use finger holes to handle, control, or throw the bowling balls. The bowling balls for this competition will roll down a ramp.
