The influence line diagram for reaction at a support of a simply supported beam is

Which of the following statements is NOT correct:

The ordinates of influence line diagram for bending moment always have the dimensions of

Read the following statements.
1) When a train of load passes through a simply supported beam the maximum bending moment occurs at the centre of the beam when the centroid of the loads and the highest wheel load are equidistant to it.
2) When a train of load passes through a simply supported beam the maximum bending moment occurs below an adjacent load (load nearer to centroid of loading system) when the centroid of the loads and that adjacent load are placed equidistant to the centre of the beam.
3) When a train of equal loads pass through a simply supported beam the maximum reaction at a support occurs when the centroid of the vehicle passes through the support.

Which of the above statements are correct?

The given figure shows a beam with its Influence line for shear force at section XX. The value of the shear force at section XX due to concentrated load of 50 kN at mid span will be

Which of the following ILD is incorrect for the given beam?

The influence line for bending moment at section X (M_X) at a distance of 4 m from the left support of a simply supported girder AB is shown in figure below. A uniformly distributed load of intensity 2 t/m longer than the span crosses the girder from left to right

The max banding moment at section X is equal to:

Three wheel loads 20 kN, 15 kN& 20 kN spaced 2m apart move across a girder of span 20m. For getting maximum bending moment at a section 8m from the left end
