A rod (mass M, length L) hinged at point X. End Y is attached to X by an elastic string passing over a pin P, the natural length of the string is L. P is a distance L from X.
Elastic Modulus of string: (1/4Mg)
Refer to GPE to X and prove that total PE is: (1/4)MgL(1-cosθ-2sinθ) and find angle θ for the equilibrium position.

I literally have no idea where to begin with this and any help at all would be greatly appreciated.
Thank you in advance.
