17. Assumptions Used
Each flex plane of coupling acts like an angular spring: Moment = Ka*Angle
Euler-Bernoullie Beam model neglecting shear
Neglect all dynamic effects

18. Comments Dynamic effects not considered
Motor and pump assumed symmetric. If not, then zero-shear at coupling does not hold. Angle seems more sensitive to deviation from symmetric.
For the combination hard coupling, soft bearing, offset created less force than angle (both thin and thick shaft)
Angle creates more bearing angle deviation than offset in most cases
Offset tends to hit the inboard bearing. Angle tends to hit both bearings. (force magnitude)
* Soft or hard coupling makes much less difference when both shaft is thin and beairngs soft.
