  • Given: D = 0.2 m, θ = 120° → semi-cone angle α = 60°, μ = 0.03, N = 500 rpm → ω = 52.36 rad/s, W = 15,000 N.
  • Concept: For uniform pressure, friction torque T_f = (2/3) μ W R / sin α, where R = radius = 0.1 m.
  • Calculation: sin 60° = 0.866.
    T_f = (2/3) × 0.03 × 15000 × 0.1 / 0.866 = 0.6667 × 450 / 0.866 = 300 / 0.866 ≈ 346.4 N·m.
  • Power lost = T_f × ω = 346.4 × 52.36 ≈ 18,140 W = 18.14 kW.
  • Common mistake alert: Using average radius instead of R or forgetting the semi-cone angle.
  • Verification using uniform wear formula: T_f = (1/2) μ W R / sin α gives 259.8 N·m → 13.6 kW. The problem specified uniform pressure, so our first answer is correct. This comparison shows why assumptions matter.
