Expert Solution

Step 1. Introduction and given data

Two frames with loading as shown given.

To determine the AFD, SFD, and BMD.

Now,

Degree of static indeterminacy, D_s

D_s= 3C-R

C = number of cuts made to make an independent tree-like structure

R = number of reactions added to make the support rigid

$\begin{array}{rcl} For frame 1, \\ D_{s} & = & 3 C - R \\ = & 3 \times 1 - (2 + 1) \\ = & 0 \end{array}$ $\begin{array}{rcl} For frame 2, \\ D_{s} & = & 3 C - R \\ = & 3 \times 0 - (0) \\ = & 0 \end{array}$

Thus, frame 1 and frame 2 are statically determinate.
