Re: Contact Area and its Relation to Friction?

Head on, 1625 did not push 217 easily. I can show you the video evidence. However, we were easily pushed sie to side for reasons completely separate from surface area and frictional force. Our side bumpers were located such that we (inadvertantly) were giving our opponents the ability to transfer our weight to them in a side pushing match, which lowered our normal force and increased our opponents normal force.

Besides, who says our robot was optimized for max pushing force last year? We had a single speed transmission that was not optimized for pushing.

The fact that your team could push the T-Chickens last year has nothing to do with the fact that surface area has nothing to do with static friction.
