Problem 30-1 The structure shown in Figure P-441 is hinged at A and C. Find the horizontal and vertical components of the hinge force at B, C, and A.

\(A_V = 20 ~ \text{kN}\) \(A_H = 17.5 ~ \text{kN}\) \(B_V = 10 ~ \text{kN}\) \(B_H = 17.5 ~ \text{kN}\) \(C_V= 10 ~ \text{kN}\) \(C_H = 17.5 ~ \text{kN}\)
