A light rigid straight beam ABC is smoothly hinged at end A on a vertical wall and supported in horizontal position by a wire which is attached to the wall and midpoint of beam b at an angle of 60degrees to the beam.
Calculate the tension in the wire and direction and magnitude of the force on the hinge when a mass M is suspended from the string
okay so I took moments about point A
Tsin60=2Mg
so T is 2Mg/sin60... T is 2.3MG
i dont get how to get the force in the wire
