P a g e | 1: we know the signs of the components of two vectors, a and b, which have equal magnitudes. The signs are: ax negative; ay positive; bx negative; by negative. Determine the coordinate direction angle of the resultant force. P a g e | 2: determine the height d of cable ab so that the force in cables ad and ac is one-half as great as the force in cable ab. P a g e | 3: a carpenter carries a uniform 6 kg board. The cable cb can sustain a maximum load of 500 n before it breaks. If f1 = 1. 5f2, determine the critical load f2. (a) 300 n (b) 110 n (c) 490 n (d) 250 n (e) 390 n. 300-kg walkway is at g, calculate the tension t in the horizontal cable. (a) 1200 n (b) 230 n (c) 1700 n (d) 2500 n (e) 850 n.
