A uniform metal rod, with a mass of 5.0 kg and a length of 2.0 m, is attached to a wall by a hinge at its base. A horizontal wire is bolted to the wall above the base of the rod and holds the rod at an angle of 30° above the horizontal. The wire is attached to the top of the rod.
(a) Find the tension in the wire.
(b) Find the horizontal and vertical components of the force exerted on the rod by the hinge. Use g = 10 m/s2.
