Question

A simply supported beam of span \(6\,\mathrm{m}\) carries a central point load. If the plastic moment capacity is \(90\,\mathrm{kN\!-\!m}\), the collapse load is

• A. \(45\,\mathrm{kN}\)
• B. \(60\,\mathrm{kN}\)
• C. \(75\,\mathrm{kN}\)
• D. \(90\,\mathrm{kN}\)

Hint:

For a simply supported beam with a central point load, \[ \boxed{ W=\frac{4M_p}{L}. } \]

Answer 1

The Correct Option is B
