My main issue here is determining the correct reaction force, I'm truly lost as to where I'm making a mistake?
The question is: A uniform rod of length 2m and mass 5kg is connected to a vertical wall by a smooth hinge at A and a wire CB as shown. If a 10kg mass is attached to D, find:
The tension in the wire (Obvious, answered on the attachment)
The magnitude of the reaction in the hinge at A (truly stuck here!)
Am i correct in assuming the forces are in equilibrium and that the reactionary force would be perpendicular to the wall itself?
Any assistance/advice would be much appreciated, I have an exam tomorrow based around these concepts. Thanks.
The attachment is my attempt so far with the desired answer for the second part in red at the bottom:
