is the pre-stressed force applied to tendon of a rectangular pre-stressed beam whose area of
cross section is and sectional modulus is . The minimum stress on the beam subjected to a
maximum bending moment is

(A) f = (P/A) - (Z/M)

(B) f = (A/P) - (M/Z)

(C) f = (P/A) - (M/Z)

(D) f = (P/A) - (M/6Z)



The correct Answer Is
(C) f = (P/A) - (M/Z)
