    for dynamically equivalence system moi of system equal to moi of original which is not in non dynamic system then how u r applying k^2=l1×l3

    - Equivalent dynamic system of two mass has three conditions should be satisfied.

    1) m = m1 + m2
    2) m1 l1 = m2 l2
    3) IG = IG1 + IG2

    - To satisfy the third condition of dynamic equivalence, correction couple is applied on arbitrarily chosen two mass system.

    - The difference between torque required to accelerate non dynamically equivalent system and dynamically equivalent system is called as correction couple.

    - The formula to calculate correction couple is given as :

    TC = ml1 (l3 – l2) α
