The maximum bending moment at the left quarter point of a simple beam ...
The maximum bending moment at a specific point on a simple beam is the point where the internal forces and moments are at their maximum. In this case, we are considering a uniformly distributed load (UDL) that is shorter than the span of the beam and is moving from left to right. We need to determine the position where the maximum bending moment occurs.
To do this, let's consider the beam with the UDL. As the UDL moves from left to right, it applies a downward force on the beam. This force creates a moment at each section of the beam, resulting in bending.
Now, let's analyze the beam at different positions of the UDL:
1. When the UDL is at the left end of the beam:
- At this position, the entire UDL is acting on the beam.
- The bending moment at this point is zero because there is no distance between the UDL and the point of interest.
2. When the UDL is at the right end of the beam:
- At this position, the UDL has just crossed the section of interest.
- The bending moment at this point is also zero because there is no distance between the UDL and the point of interest.
3. When the UDL is at any other position between the left and right ends of the beam:
- At this position, a part of the UDL is acting on the beam.
- The bending moment at this point is not zero because there is a distance between the UDL and the point of interest.
Based on the above analysis, we can conclude that the maximum bending moment occurs when the UDL has crossed three-fourths of its length. At this position, a significant portion of the UDL is acting on the beam, creating a larger moment compared to the other positions.
Therefore, the correct answer is option 'C' - Three-fourth of its length.

Therefore, the correct answer is option 'C' - Three-fourth of its length.
