Answer :
Answer:
[tex]K=2J-R[/tex]
Explanation:
Let [tex]R[/tex] denotes the number of sides of a triangle.
Let [tex]J[/tex] denotes the number of joints.
Let [tex]M[/tex] denotes the number of members.
Let [tex]K[/tex] denotes the unknown to be solved.
Now write the structural stability formula:
[tex]K=2J-R[/tex]
Here, design is stable if [tex]M=K[/tex]
Design is unstable if [tex]M<K[/tex]
Design is indeterminate if [tex]M>K[/tex]
