If is the sectional area of a pre-stressed rectangular beam provided with a tendon pre-stressed by a force through its centroidal longitudinal axis, the compressive stress in concrete, is
A)P/A
B)A/P
C)P/2A
D)2A/P

Question

Quizplus · Accepted Answer

The compressive stress in concrete due to a pre-stressing force (P) applied through the centroidal longitudinal axis of a rectangular beam is given by the formula σ = P/A, where σ is the stress, P is the pre-stressing force, and A is the sectional area of the beam.
