节选段落一：
With these corrections, dP = 2.6
Check assumptions for
Cv
Cm
and
F = dP = 2.6
Cm = 1.61
(1.6 was assumed)
Select dP = 2.75 and A-3 steel as the material
Qv = 10
Cv = .9 (.9 was assumed)
Design Example
Bending failure
For A-3 material, St = 36,000 – 47,000 psi
Use 36,000 psi in calculation
Assume J = .4,


节选段落二：
check later
For power transmission, 2 ≤ P ≤ 16, so select P = 16
Wt = (33000) hp / V
Wt = (33000) 25 / 680
Wt = 1213 lb
1213(1/.9)(P /2.75)(1.6)(1/.4) = 36,000
P = 18.3
Design Example
Check assumption for J
NP = P dP = 16 x 2.75 = 44
NG = P dG = 16 x (2.75x2) = 88
J = .43
P = 19.7
So P = 16 is valid
