The results indicate that elastic modulus, the angle of internal friction, and cohesive stress of the backfill are main factors affecting the stability of the slope.

结果表明，土体的弹性模量、内摩擦角与粘聚力是影响边坡位移的重要因素。

Then there's the Slide (pictured above) which relies on interesting physics to support the iPad: a heavy high-friction rubber cylinder is pulled out of its tubular compartment under the metallic slope, and it can be placed anywhere on the slope to support the iPad at any desired angle, up to somewhere around 70 degrees -- you can see it and the others in action in the earlier video.
