F D 2b b K b TQ The reaction force A = The reaction force A, = The pin force B = The pin force C, on the beam ABC = The pin force D, on the beam DBE = R a Determine the forces in each pin-joint of the beams ABC and EBD, when the given loadings are F = 3 kN, Q = 2 kN and R = 2 kN and the dimensions a = 3 m and b= 1 m. You may give the force results as positive values. KN kN kN kN kN
