A small ring of negligible weight at point C is acted upon by the four forces as shown below. There are two cables AC and BC, force Q, and force P. The force P is downward, the force Q is collinear with the force in cable BC. The ring is in static equilibrium. a) Determine the tensile forces in both cables in terms of Q and P (parameters). b) Calculate the forces in both cables if Q = 140 lbf and P = 220 lbf. c) Using Q = 140 lbf, determine the range of values for P such that the tensile force will not exceed Tmax = 350 lbf in either cable. Hint: solve a system of two inequalities Tac
