Question

An $8$ m long simply-supported elastic beam of rectangular cross-section ($100$ mm $\times 200 $mm) is subjected to a uniformly distributed load of $10$ kN/m over its entire span. The maximum principal stress (in MPa, up to two decimal places) at a point located at the extreme compression edge of a cross-section and at $2$ m from the support is _______

Answer 1

Shear stress is zero at extreme edge is 0. Bending stress is only stress present and it's value is 90mpa hence principal stress is 90mpa

You may debate it as official key says 0.

How to debate?

Answer 2

the answer should be 90MPA
