Homework Equations
The Attempt at a Solution
iv had a go at this and I think I am getting it right but just looking for a bit of clarification since my lecturer isn't giving out answers, helpfull...
ive started off by saying that initially the system is stationary and equilibrium so,
K.X_in = M.G
X_in = (M.G)/K
so MGR - K(X_in+X)R=I(alpha) sub in X_in = (M.G)/K
(MGR) - ((KMGR)/K) - (KXR) = I(alpha) simplify and sub in X=R(theta)
so,
K(R^2)(theta) + I(alpha) = 0
so (omega_N) = R SQRT(K/I)?
any help would be very very helpful!
