Instructions

On the instructions for Mission Possible it states, "An object must be continuously pushed or pulled without rolling along a stationary Inclined Plane," what does this mean?

To explicate Unome's directions, you're gonna want either a flat - based object (cube/prism) or a ball that is pulled by an attached string. And the incline should be non-moving. Otherwise, if it tilts and the ball/object slides off, it is a lever, your TSL is technically wrong, and you lose good points. So drill it in well.

Disclaimer

Most likely that the object has to slide, i.e. it shouldn't be a round object. Theoretically a round object could be legal if it never rolled while traveling up the ramp (do the rules still say it has to travel up only, and not down? I don't have rules for this year yet) but I highly advise you to play it safe and use an object that wouldn't roll in any circumstances. Also that the inclined plane can't move in order to force the object upward, although that's probably far less likely to be attempted.

So a car would be ok?

A car with rotating wheels would not be okay, because it is rolling. In fact, I think the rules this year were explicitly written to exclude cars as legal objects to go up the inclined plane. There was a lot of confusion last year about whether a car going up an inclined plane counted as an wheel and axle (it didn't).

I did see some "nearly flat inclined planes" last year. This year is much more of a challenge in that regard.
