Titanium is highly flexible, so it offers better shock absorption than carbon fiber. Carbon, on the other hand, doesn't deform under load linearly. The lack of deformity aspect on carbon means that it generates a harder impact, consequently a harsher ride.

In general, a grade 7-9 is roughly equivalent to A-A* under the old system, while a grade 4 and above is roughly equivalent to a C and above. Fewer students will receive a grade 9 than would have received an A* under the old grading system.

Grade 3 shows thinning of cartilage with active deterioration of the tissue. Grade 4, the most severe grade, indicates exposure of the bone with a significant portion of cartilage deteriorated. Bone exposure means bone-to-bone rubbing is likely occurring in the knee.

A diagnostic level of 500 in a strand represents a readiness to begin working on fifth-grade level skills. If a student's number is 550, it indicates the student is halfway through the fifth-grade level. A 750 indicates the student is halfway through the seventh-grade level.

Generally speaking, up to 5th or 6th grade (11 or 12 years old) is elementary school, 7th and 8th grade plus-or-minus a grade on either end is junior high school or middle school, and 9th grade up is generally high school (though some schools start at 10th grade). ... sophomore year = 10th grade.

Putting in some typical dimensions and material properties we find that the stresses in a bone made from titanium alloy, for example, would be about 1.3 times higher than in a bone of the same weight, made from bone. But the titanium alloy is 5 times stronger so obviously its safety factor is much higher.
