How should i setup the force diagram and conditions of equilibrium?
a uniform beam of mass m pivoted at its lower end, with a horizontal spring attached between its top end and a vertical wall. The beam makes an angle θ with thehorizontal. Find expressions for (a) the distance d the spring is stretched from equilibrium and (b) the components of the force exerted by the pivot on thebeam.
The correct answers are (a) d = mg/(2k tan θ) (b) Rx = Ry = mg
