A curved bar is supported by a roller at A and a pin at B. Determine the magnitude of the reaction(s) at A. 

I approached this problem by taking moment about B to find Ay. This is my equation 

8.5−(Ay​)(2.375)+(6.5)(3.75)−(3)(1)−(1.5)(0.5)=0 

I get 12.26 kN which is not correct. What am I missing here? The answer choices are 5.2 kN, 1.3 kN, 2.35 kN, and 10.6 kN. I'm guessing 1.3 kN based on the equilibrium equation for sum of y: Ay + By = 3.5 kN
