Discuss the below:
Q: A slender rod AB of mass m is attached to two blocks A and B that can move freely in the guides shown. Knowing that the spring is unstretched when AB is horizontal, determine three values of θ corresponding to equilibrium when m = 125kg, l = 320 mm, and k = 15kN/m. State in each case whether the equilibrium is stable, unstable, or neutral.
