The allowable limits of Shearing Force and Bending Moments are the values which the structure of the ship is designed to take. The Ship’s capacity to bear SF and BM depends upon its sectional properties (differs from ship to ship).
This capacity of the ship to take sheer and bending moment varies from one longitudinal location to other. These values are stated in the Stability Booklet of the vessel and depends upon the Classification Society Rules which lays down such requirements. The values of SF/BM are in Newton-Metre and is defined on a scale of 0% to 100% on loadicator. A ship will always have some value of stress so the value can never be 0%. But in any case it should never exceed 100%.
