This paper presents an analysis method for the acting mechanism of bolts in soft rock. The mechanical behaviors of rock bolting system and bolt itself are discussed respectively.

Notice that the axle bolt is higher than where the cams touch the rock. This is what provides the (approximately) 4:1 mechanical advantage that keeps the CAM secure, even in a smooth, parallel crack.
