Uniform rod AB of length l and mass m lies in a vertical plane and is acted upon by a couple M. The ends of the rod are connected to small rollers which rest against frictionless surfaces.
(a) Express the angle θ corresponding to equilibrium in terms of M, m, g, and l.
(b) Determine the value of θ corresponding to equilibrium when 2.7 M= N ∙ m, m = 2 kg, and l = 0.8 m.
