A prismatic cantilever prestressed concrete beam of span length L = 1.5 m has one straight tendon place in the cross-section as shown in the figure (not to scale). The total prestressing force of 50 kN in the tendon is applied at dc = 50 mm for the top in the cross-section of width, b = 200 mm and depth, d = 300 mm.
If the concentrated load, P = 5 kN, the resultant stress (in MPa, in integer) experienced at point 'Q' will be _________.
    Correct answer is '0'. Can you explain this answer?

    Let T = top and B = bottom
    Consider a cross-section element at Q.
    MOI of C/S (1) =
    = 450 × 106 mm4
    Section modulus (Z) =
    = = 3 × 106 mm4
    Note: For rectangular cross-section.
    Section modulus (Z) = = 3 × 106 mm4
    'Q' is the top point.
    Stress at top, (σT)
    = 0.833 + 1.667 - 2.5 = 0
    Resultant stress at 'Q', rounded off, in integer = 0
