is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is and sectional modulus is. The maximum stress in the beam, subjected to a maximum bending moment, is________?
Af = (P/A) + (M/6Z)
Bf = (A/P) + (M/Z)
Cf = (P/A) + (M/Z)
Df = (P/A) + (Z/M)
Correct answer
C. f = (P/A) + (M/Z)
Explanation
The correct answer is f = (P/A) + (M/Z).
