103
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
[A]
f = (P/A) + (Z/M)
[B]
f = (A/P) + (M/Z)
[C]
f = (P/A) + (M/Z)
[D]
f = (P/A) + (M/6Z)
Answer: f = (P/A) + (M/Z)
