Answer (Detailed Solution Below)
Detailed Solution

In case of a simply supported beam subjected to a concentrated moving load:
- The maximum bending moment occurs when the load is applied at mid-span and it will occur at mid-span itself.
- The maximum shear force will occur when the load is applied at any one of the support and it will occur near the support itself.
Calculation:
Given data,
P = 8 kN
L = 15 m
For maximum bending moment load is applied at mid span
Mmax = PL/4 = (8 × 15)/4 = 30 kN-m
