(b) Determine the safety factor against sliding failure for the gravity retaining wall shown in Figure S4(b). Unit weight of wall materials/ Berat unit dinding bahan-bahan, y = 24 kN/m³ $ = 30° C = 0 = 19.0 kN/m³ 4.8m 1.2m 2.4m Rajah S4(b)/Figure S4(b) 2.4m c= 50 kN/m² $ = 20° y = 18.0 kN/m³ 8 = 0.60
