Question:

As shown in Fig. P2.10, an elastic exercise band is grasped and then is stretched. Knowing that the tension in portion DE of the band is 70 N, determine, using trigonometry,

(a) The magnitude and direction of the smallest force in portion BC of the band for which the resultant R of the two forces exerted on the hand at A is directed along a line joining points A and H,

(b) The corresponding magnitude of R.

As shown in Fig. P2.10, directed along a line joining points A
