   The factor of safety of a slope of given inclination of 6 m high constructed using a soil with c=60 kPa, γ=20 kN/cum and its Taylor's stability number=0.20, will be:

   1. 2.50
   2. 5.00
   3. 1.00
   4. 2.00
   Show answer

   Answer: (1) 2.50

   Mobilised cohesion c_m = S_n γ H = 0.20 × 20 × 6 = 24 kPa. Factor of safety = c/c_m = 60/24 = 2.50.
