Q.

The frictional torque transmitted in a truncated conical pivot bearing, considering uniform pressure, is

  • A(1/2). μ W cosecα (r₁ + r₂)
  • B(2/3). μ W cosecα (r₁ + r₂)
  • C(1/2). μ W cosecα [(r₁³ - r₂³)/(r₁² - r₂²)]
  • D(2/3). μ W cosecα [(r₁³ - r₂³)/(r₁² - r₂²)]
Correct Answer : (D)

(2/3). μ W cosecα [(r₁³ - r₂³)/(r₁² - r₂²)]
