Q. 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 (Solved)
1. f = (P/A) +(Z/M)
2. f = (A/P) +(M/Z)
3. f = (P/A) + (M/Z)
4. f = (P/A) + (M/6Z)
- c. f = (P/A) + (M/Z)
