2.5.2. Axial Load and Moment Load
 The following show how to calculate axial and moment loads.

(1) When F is the external force, then

Axial load Fa = F + weight of paylaod.

Moment load M = 0
(2) When an extyernal force is F, then

Axial load FA = F + weight of payload

Moment load M = F × L
(3) When an external force is F, then

Radial load Fr
＝
F + weight of payload

Moment load M = F × (L

Caution : Axial load Fa, radial load Fr and moment load M shall be less than the
limits specified in the table 2-5 and 2-6 respectively.
