The cable in Figure 1 is subjected to two concentrated loads at B and C. The values of the load are P = 5*SN (KN) and P = 3*SN (kN). The lengths of the cable are L = 0.1*SN (m), L= 0.4*SN (m) and L3 = 0.2*SN (m). The sag of the cable at C is h=0.5*SN (m). The cable is pin supported at A and D. (25 Marks) SN=23 (a) Calculate the tension in the cable segments AB, BC and CD. (b) Determine the reaction forces at supports A and D. (c) Calculate the sag of the cable at B (y).
