Downforce on wheels = 130 + 100 + 100 = 330 lbs.

So... essentially, with both suction cups engaged and the cylinders pulling up, their robot weighs 330 lbs. Although it's not best design practice to simply let the cylinder shaft support the side loads on the vacuum cups, it's the wheels that are exerting the downforce, not the cups. An opposing team not only has to slide the suction cups, but also 330 lbs. of downforce applied to their wheels.

In order to push this robot, an opposing robot has to push with more force than this robot's holding force (at least that's what I call it). Their holding force = 330 lbs. x mu (their wheel's coefficient of friction).

again this all relates to the orientation of the robot...sheer vs. tension. it also relates to how fast the other robot is going and how concentrated the force is (remember, force and pressure are not the same thing).

P.S. Our wheels are made of (insert words here), they are 6 inches in diameter and are 2 inches wide..... [/b]

6 x 2 is wide, but you have a small wheel compared to many teams...we have some wheels made out of err...rubber? that are 8" x 2". not that it gives you more traction, just faster speeds.
