Question

Absolute maximum bending moment under any given wheel in a beam due to several point loads occurs when:

• A. none of the above
• B. this wheel and the maximum load wheels are equidistant from the ends of the beam
• C. this wheel is at mid-span
• D. this wheel and centre of gravity of the total load system are equidistant from the ends of the beam

Answer 1

The correct option is A none of the above

Absolute maximum bending moment occurs when position of load is such that centre of span is mid way between C.G of load group and load under consideration.
