Expert Solution
Step 1 Introduction and given data

A frame hinged at the bases.

A horizontal load of 5 kN acts at the mid of the right span and a UDL of 3 kNm acts on the beam.

Degree of static indeterminacy, Ds

Ds= 3C-R

Where

C = number of cuts to make a tree-like structure

R = number of reactions added to make the frame rigid

Ds= 3C-R=3×1-2=1

Thus, the degree of static indeterminacy is 1, we need a compatibility equation to determine the support reaction.

To determine support reactions and draw an axial force diagram, SFD, and BMD.
