# Weight of goal w/ balls in it

Other on team #639, Red B^2, from Ithaca High School and Cornell University.

Has anyone measured / calculated the weight of the goal and/or the weight of the small balls and big balls? The center of mass of the goal? Our team is in need of this information to calculate torques and whatnot.

Thanks

i think someone said that the goal was 88lbs full, but what that ‘full’ entails, and wether or not my memory is accurate is subject to debate (what DID i do last night?..)

Patrick,

Our goal, with 13 small balls (which lets a big ball seat on top with no interference) and one big ball weighs around 85 lbs. The CG of the empty goal is about 24 inches above the floor. Good luck.
