Concept:

If, m = (2j - 3) ⇒ Perfect, stable truss

If, m < (2j - 3) ⇒ Deficient or Unstable truss

If, m > (2j - 3) ⇒ Redundant or Indeterminate truss

Where,

m = Total number of member

j = Total number of joint

Calculation:

F1 Eng Priyas 13 9 24  D1

m = 6 , j = 5

2j - 3 = 2 × 5 - 3 = 7

So, m < 2j - 3 ⇒  Deficient or Unstable truss
