Deflection Calculation

Use this formula:

D = N x W x L3
Where:
N = value from the chart below
W = load in pounds
L = length (in inches) of unsupported shaft section
"N" VALUE FOR NOOK SHAFTS
Shaft Diameter (in.) Simple Fixed
1/4 3620 x 10-9 905 x 10-9
3/8 715 x 10-9 179 x 10-9
1/2 226 x 10-9 56.6 x 10-9
3/4 44.7 x 10-9 11.2 x 10-9
1 14.1 x 10-9 3.54 x 10-9
1 - 1/2 2.79 x 10-9 .698 x 10-9
2 0.866 x 10-9 .0220 x 10-9
3 0.168 x 10-9 .432 x 10-10
4 0.052 x 10-9 .136 x 10-10
