The cylinders in the figure have the indicated weightsand dimensions. Assuming smooth contact surfaces, determine the reactions at A,B, C, and D on the cylinders.NOTE : see fig-13 from the LIST OF FIGURES in Week-1 

• A = 4739 kN, B = 60 kN, C = 4085 kN, D = 4739 kN
• A = 34739 kN, B = 600 kN, C = 40085 kN, D = 34739 kN Correct
• A = 3739 kN, B = 6000 kN, C = 400085 kN, D = 3739 kN
• none of the choices
