Answer is:
non-equilibrium
Answer is:
2j-3
Explanation:
A perfect frame is that which is composed of members just sufficient to keep it in equilibrium, when loaded, without any change in its shape. A perfect frame should satisfy the following expression:
n = 2j-3
where
n = Number of members, and
j = Number of joints.
