Question

Quizplus · Accepted Answer

The depth of the critical neutral axis of a beam is given by the formula [m/(m + r)] d, where m is the modular ratio, r is the steel ratio, and d is the overall depth of the beam. This formula accounts for the different materials used in the beam, typically concrete and steel, by adjusting the neutral axis position according to their properties.
