5.
The section modulus of a rectangular light beam 25 metres long is 12.500 cm3. The beam is simply supported at its ends and carries a longitudinal axial tensile load of 10 tonnes in addition to a point load of 4 tonnes at the centre. The maximum stress in the bottom most fibre at the mid span section, is
13.33 kg/cm2 tensile
13.33 kg/cm2 compressive
26.67 kg/cm2 tensile
26.67 kg/cm2 compressive
none of these.

Question is wrong ,there is needed cross-sectional area, not given so we can't find the answer.

B.S = M/Z + P/A.
M = WL/4.

But A is not given.
