# Questions & Answers of Influence lines for determinate structures

Consider the beam ABCD shown in the figure.

For a moving concentraed load of 50kN on the magnitude of the maximum bending moment (in kN-m) obtained at the support C will be equal  to ____________

##### Show Answer

In a beam of length L, four possible influence line diagrams for shear force at a section located at a distance of $\frac{L}{4}$ from the left end support (marked as P, Q, R and S) are shown below. The correct influence line diagram is

##### Show Answer

Beam PQRS has internal hinges in spans PQ and RS as shown. The beammay be subjeted to a moving distributed vertical load of maximum intensity 4 kN/m of any length anywhere on the beam. The maximum absolute value of the shear force (in KN) that can occur due to this loading just to the right of support Q shall be:

##### Show Answer
