is this the beam with hinges?
take the curvature and multiply it by the hinge length.

Sir I figured out the same. Is the curvature constant over the plastic hinge length?since the curvature is not constant over the length by multiplying the curvature by the pl hinge length the result will not be accurate......
Can you please clarify this?
