A beam of uniform strength has a cross-section designed such that maximum bending stress developed is:
AZero throughout the length
BMaximum at midspan and zero at supports
CConstant at all sections along the span
DProportional to shear force
Explanation
A beam of uniform strength is configured (by varying cross-sectional width or depth along its length) so that extreme fiber bending stress remains constant across all sections along the span under design load.
