Wire is being drawn at a constant rate from a spool by applying a vertical force P to the wire as shown. The spool and the wire wrapped on the spool have a combined weight of 20 lb. Knowing that the coefficients of friction at both A and B are Î¼s = 0.40 and Î¼k = 0.30, determine the required magnitude of the force P.
