When the weight of block B to maintain equilibrium is maximum,
the tensile forces in the four segments of the cord are
π1, π2, π3 πππ π4, as
indicated in the figure. Determine the values of these four tensile
forces, in N, and the mass of block B, in kg. Use π = 9.81
π/π 2. Draw all necessary free-body diagrams and indicate
the direction of impending motion. Also, show the diagrams in
finding the angle of wrap, π½ for each pulley.
