∑Fy = 0 = Ay + By - 20 kN Ay = 20 kN - By = 20 kN - 10 kN = 10 kN Structural Analysis R C Hibbeler 8th Edition Solution

1.1 : Determine the reaction at the supports of the beam shown in Fig. P1-1. Step 1: Determine the support reactions The beam is supported by a pin at A and a roller at B. The sum of the moments about A is: ∑MA = 0 = - (12 kN)(3 m)

∑MA = 0 = - (20 kN)(4 m) + By(8 m) By = (20 kN)(4 m) / 8 m = 10 kN Step 3: Determine the reaction at A The sum of the forces in the y-direction is: The sum of the moments about A is:
