(A) For the beam to be in equilibrium,the net force and net torque acting on it must be zero.$1$. The forces acting on the beam are: the weight $W$ acting downwards at the center of mass,the tension $T$ in the rope acting along the rope,and the reaction force $R$ at the hinge $H$.$2$. Since the beam is in equilibrium,the lines of action of all three forces must intersect at a single point.$3$. The weight $W$ acts vertically downwards through the center of the beam. The tension $T$ acts along the rope towards the wall.$4$. The intersection point of the weight vector and the tension vector lies somewhere above the beam. For the reaction force $R$ to pass through this same intersection point,it must be directed upwards and towards the right,as shown in option $A$.

$A$ uniform beam of weight $W$ is attached to a vertical wall by a hinge $H$. The beam is held horizontal by a rope as shown below. Which one of the following best shows the direction of the reaction force $R$ at the hinge?
