Expert Solution
Step 1 Introduction

Given: A simply supported truss in the figure

Method used: Method of section because only in few members force is to determine not in all members.

Check for indeterminacy:

Truss will be determinate when m≤2j-3

Where, m = Number of members

j = Number of joints 

Number of members m=13

Number of joints j=8

2j-3=28-32j-3=13

Since, m=2j-3=13

Therefore, the truss is statically determinate.
