Three wheel loads 10t, 26t and 24t spaced 2m apart roll on a girder from left to right with the 10t load leading. The girder has a span of 20 meter. For the condition of maximum bending moment at a section 8 meter from the left end.
- a)The 10t load should be placed at the section.
- b)The 26t load should be placed at the section.
- c)The 24t load should be placed at the section.
- d)Either the 26t load or the 24t load should be placed at the section.
Correct answer is option 'B'. Can you explain this answer?

Maximum bending moment at a section occurs when a particular load is on the section which changes the ratio 
as the load passes over the section .
where R1, → resultant of load on left sid e of section Resultant of all loads (R)
= 10 + 26 + 24 = 60t
When 10t load crosses section C.
When 26t load crosses the section C,
It means that maximum bending moment is obtained when 26t load is on the section.

Given Data:
Three wheel loads: 10t, 26t, and 24t
Distance between loads: 2m
Span of girder: 20m
Section for maximum bending moment: 8m from the left end
To find: Which load should be placed at the section for maximum bending moment?
Solution:
1. Calculation of reactions at supports:
Total weight of loads = 10t + 26t + 24t = 60t
∴ Reaction at each support = Total weight/2 = 30t
2. Calculation of position of loads:
Let the distance of the 10t load from the left support be x
∴ distance of 26t load from left support = x + 2
distance of 24t load from left support = x + 4 + 2 = x + 6
Total distance between the 10t load and the right support = (20 – x)
∴ Distance between the 26t and 24t loads = (20 – x) – (x + 2) = 18 – x
3. Calculation of Shear force and Bending Moment:
At x = 8m,
Shear Force = 30t (due to 10t load)
Bending Moment = 30t × 8m – 10t × 6m = 180t-m
At x = 8m,
Shear Force = 30t + 10t = 40t (due to 10t and 26t loads)
Bending Moment = 40t × 8m – 10t × 6m – 26t × 4m = 128t-m
At x = 8m,
Shear Force = 30t + 10t + 26t = 66t (due to all loads)
Bending Moment = 66t × 8m – 10t × 6m – 26t × 4m – 24t × 2m = 200t-m
Conclusion:
From the above calculations, it can be observed that the bending moment is maximum when the 26t load is placed at the section, i.e. option B is the correct answer.
