Question:

Two 2.4-in.-diameter pegs are mounted on a steel plate at A and C. and two rods are attached to the plate at B and D. A cord is passed around the pegs and pulled as shown, while the rods exert on the plate 2.5-lb forces as indicated.

(a) Determine the resulting couple acting on the plate when T = 9 lb.

(b) If only the cord is used, in what direction should it be pulled to create the same couple with the minimum tension in the cord?

(c) Determine the value of that minimum tension.
