Costs range between $700 for the non-digital Queen c2 model to nearly $5,000 for the top of the line i10 model mattress.
A C1 crampon is designed for very basic hiking while C2 is suitable for moderate skill-level mountaineering.
For example, if you have a B2 boot, you could use a C2 or C1 crampon.
Crampons are marked with grades C1, C2 and C3.
Hence the note produced with any given circle of holes rises in pitch as the disk revolves more rapidly; and if, the revolution of the disk being kept as steady as possible, the tube be passed rapidly across the circles of the first series, a series of notes is heard, which, if the lowest be denoted by C, form the sequence C, C1, El, G1, C2, &c. In like manner, the first circle in which we have two sets of holes dividing the circumference, the one into say 8 parts, and the other into Io,.
(16) Along the path of a liquid particle 4)' is constant, and putting it equal to 2Uc2, (r 2 - a 3 /r) sin 2 0 = c 2, sin 2 0 = c2r/(r3 - a3), (17) the polar equation; or y 2 = c2r3/(r3 - a 3), r3 = a3y2 /(y2._ c2), (18) a curve of the 10th degree (C10).
U=cv~-+-a To apply this to involute teeth, let ci be the length of the approach, c2 that of the recess, u1, the mean volocity of sliding during the approach, u2 that during the recess; then civil i\ c,v/1 I
The effective angular inertia of the body in the medium is now required; denote it by C 1 about the axis of the figure, and by C2 about a diameter of the mean section.
Let v be the common velocity of the two pitch-circles, ri, C2, their radii; then the above equation becomes /1 I
A 41311 (56C 1 - 28C 2 + 8C 3 - C4) C1+2(Ci - C2) - (C2 - C3) + s i s(C3 - C4).
