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,

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

The correct Answer Is
(A) P/A
 
lf 'A' is the sectional area of a prestressed rectangular beam, provided with a tendon prestressed by a force 'p' *vs'rgh its centroidal axis, the compressive stress induced in concrete is
