Two smooth circular cylinders, each of weight \( W=100 kg \) and radius \( r =15 cm \) are connected at their ends by a string \( AB \) of length \( l =40 cm \) and rest upon a horizontal plane, supporting above them a third cylinder of weight \( Q=200 \) \( kg \) and radius \( r =15 cm \) as shown in fig.02. Evaluate the tensile force \( S \) in the string \( A B \) and the pressure produced on the floor at points of contact D \& E.
